The book of Ether lays out the process the brother of Jared went through of ultimately piercing the veil. I don’t think much commentary is needed to recognize, and ponder the attitude we need to do likewise.
Ether chapter 1
34 And the brother of Jared being a large and mighty man, and a man highly favored of the Lord, Jared, his brother, said unto him: Cry unto the Lord, that he will not confound us that we may not understand our words.
35 And it came to pass that the brother of Jared did cry unto the Lord, and the Lord had compassion upon Jared; therefore he did not confound the language of Jared; and Jared and his brother were not confounded.
36 Then Jared said unto his brother: Cry again unto the Lord, and it may be that he will turn away his anger from them who are our friends, that he confound not their language.
37 And it came to pass that the brother of Jared did cry unto the Lord, and the Lord had compassion upon their friends and their families also, that they were not confounded.
38 And it came to pass that Jared spake again unto his brother, saying: Go and inquire of the Lord whether he will drive us out of the land, and if he will drive us out of the land, cry unto him whither we shall go. And who knoweth but the Lord will carry us forth into a land which is choice above all the earth? And if it so be, let us be faithful unto the Lord, that we may receive it for our inheritance.
39 And it came to pass that the brother of Jared did cry unto the Lord according to that which had been spoken by the mouth of Jared.
40 And it came to pass that the Lord did hear the brother of Jared, and had compassion upon him, and said unto him:
Ether chapter 2
4 And it came to pass that when they had come down into the valley of Nimrod the Lord came down and talked with the brother of Jared; and he was in a cloud, and the brother of Jared saw him not.
5 And it came to pass that the Lord commanded them that they should go forth into the wilderness, yea, into that quarter where there never had man been. And it came to pass that the Lord did go before them, and did talk with them as he stood in a cloud, and gave directions whither they should travel.
14 And it came to pass at the end of four years that the Lord came again unto the brother of Jared, and stood in a cloud and talked with him. And for the space of three hours did the Lord talk with the brother of Jared, and chastened him because he remembered not to call upon the name of the Lord.
15 And the brother of Jared repented of the evil which he had done, and did call upon the name of the Lord for his brethren who were with him. And the Lord said unto him: I will forgive thee and thy brethren of their sins; but thou shalt not sin any more, for ye shall remember that my Spirit will not always strive with man; wherefore, if ye will sin until ye are fully ripe ye shall be cut off from the presence of the Lord. And these are my thoughts upon the land which I shall give you for your inheritance; for it shall be a land choice above all other lands.
18 And it came to pass that the brother of Jared cried unto the Lord, saying: O Lord, I have performed the work which thou hast commanded me, and I have made the barges according as thou hast directed me.
22 And he cried again unto the Lord saying: O Lord, behold I have done even as thou hast commanded me; and I have prepared the vessels for my people, and behold there is no light in them. Behold, O Lord, wilt thou suffer that we shall cross this great water in darkness?
25 And behold, I prepare you against these things; for ye cannot cross this great deep save I prepare you against the waves of the sea, and the winds which have gone forth, and the floods which shall come. Therefore what will ye that I should prepare for you that ye may have light when ye are swallowed up in the depths of the sea?
Ether chapter 3
1 And it came to pass that the brother of Jared, (now the number of the vessels which had been prepared was eight) went forth unto the mount, which they called the mount Shelem, because of its exceeding height, and did molten out of a rock sixteen small stones; and they were white and clear, even as transparent glass; and he did carry them in his hands upon the top of the mount, and cried again unto the Lord, saying:
2 O Lord, thou hast said that we must be encompassed about by the floods. Now behold, O Lord, and do not be angry with thy servant because of his weakness before thee; for we know that thou art holy and dwellest in the heavens, and that we are unworthy before thee; because of the fall our natures have become evil continually; nevertheless, O Lord, thou hast given us a commandment that we must call upon thee, that from thee we may receive according to our desires.
3 Behold, O Lord, thou hast smitten us because of our iniquity, and hast driven us forth, and for these many years we have been in the wilderness; nevertheless, thou hast been merciful unto us. O Lord, look upon me in pity, and turn away thine anger from this thy people, and suffer not that they shall go forth across this raging deep in darkness; but behold these things which I have molten out of the rock.
4 And I know, O Lord, that thou hast all power, and can do whatsoever thou wilt for the benefit of man; therefore touch these stones, O Lord, with thy finger, and prepare them that they may shine forth in darkness; and they shall shine forth unto us in the vessels which we have prepared, that we may have light while we shall cross the sea.
5 Behold, O Lord, thou canst do this. We know that thou art able to show forth great power, which looks small unto the understanding of men.
6 And it came to pass that when the brother of Jared had said these words, behold, the Lord stretched forth his hand and touched the stones one by one with his finger. And the veil was taken from off the eyes of the brother of Jared, and he saw the finger of the Lord; and it was as the finger of a man, like unto flesh and blood; and the brother of Jared fell down before the Lord, for he was struck with fear.
7 And the Lord saw that the brother of Jared had fallen to the earth; and the Lord said unto him: Arise, why hast thou fallen?
8 And he saith unto the Lord: I saw the finger of the Lord, and I feared lest he should smite me; for I knew not that the Lord had flesh and blood.
9 And the Lord said unto him: Because of thy faith thou hast seen that I shall take upon me flesh and blood; and never has man come before me with such exceeding faith as thou hast; for were it not so ye could not have seen my finger. Sawest thou more than this?
10 And he answered: Nay; Lord, show thyself unto me.
11 And the Lord said unto him: Believest thou the words which I shall speak?
12 And he answered: Yea, Lord, I know that thou speakest the truth, for thou art a God of truth, and canst not lie.
13 And when he had said these words, behold, the Lord showed himself unto him, and said: Because thou knowest these things ye are redeemed from the fall; therefore ye are brought back into my presence; therefore I show myself unto you.
14 Behold, I am he who was prepared from the foundation of the world to redeem my people. Behold, I am Jesus Christ. I am the Father and the Son. In me shall all mankind have life, and that eternally, even they who shall believe on my name; and they shall become my sons and my daughters.
15 And never have I showed myself unto man whom I have created, for never has man believed in me as thou hast. Seest thou that ye are created after mine own image? Yea, even all men were created in the beginning after mine own image.
16 Behold, this body, which ye now behold, is the body of my spirit; and man have I created after the body of my spirit; and even as I appear unto thee to be in the spirit will I appear unto my people in the flesh.
17 And now, as I, Moroni, said I could not make a full account of these things which are written, therefore it sufficeth me to say that Jesus showed himself unto this man in the spirit, even after the manner and in the likeness of the same body even as he showed himself unto the Nephites.
18 And he ministered unto him even as he ministered unto the Nephites; and all this, that this man might know that he was God, because of the many great works which the Lord had showed unto him.
19 And because of the knowledge of this man he could not be kept from beholding within the veil; and he saw the finger of Jesus, which, when he saw, he fell with fear; for he knew that it was the finger of the Lord; and he had faith no longer, for he knew, nothing doubting.
20 Wherefore, having this perfect knowledge of God, he could not be kept from within the veil; therefore he saw Jesus; and he did minister unto him.
21 And it came to pass that the Lord said unto the brother of Jared: Behold, thou shalt not suffer these things which ye have seen and heard to go forth unto the world, until the time cometh that I shall glorify my name in the flesh; wherefore, ye shall treasure up the things which ye have seen and heard, and show it to no man.
22 And behold, when ye shall come unto me, ye shall write them and shall seal them up, that no one can interpret them; for ye shall write them in a language that they cannot be read.
23 And behold, these two stones will I give unto thee, and ye shall seal them up also with the things which ye shall write.
24 For behold, the language which ye shall write I have confounded; wherefore I will cause in my own due time that these stones shall magnify to the eyes of men these things which ye shall write.
25 And when the Lord had said these words, he showed unto the brother of Jared all the inhabitants of the earth which had been, and also all that would be; and he withheld them not from his sight, even unto the ends of the earth.
26 For he had said unto him in times before, that if he would believe in him that he could show unto him all things—it should be shown unto him; therefore the Lord could not withhold anything from him, for he knew that the Lord could show him all things.
27 And the Lord said unto him: Write these things and seal them up; and I will show them in mine own due time unto the children of men.
28 And it came to pass that the Lord commanded him that he should seal up the two stones which he had received, and show them not, until the Lord should show them unto the children of men.
These verses show an attitude required to connect with heaven, of crying to the Lord, of real intent.
Moroni goes on to explain what these things can mean for us, if we do likewise.
Ether chapter 4
4 Behold, I have written upon these plates the very things which the brother of Jared saw; and there never were greater things made manifest than those which were made manifest unto the brother of Jared.
5 Wherefore the Lord hath commanded me to write them; and I have written them. And he commanded me that I should seal them up; and he also hath commanded that I should seal up the interpretation thereof; wherefore I have sealed up the interpreters, according to the commandment of the Lord.
6 For the Lord said unto me: They shall not go forth unto the Gentiles until the day that they shall repent of their iniquity, and become clean before the Lord.
7 And in that day that they shall exercise faith in me, saith the Lord, even as the brother of Jared did, that they may become sanctified in me, then will I manifest unto them the things which the brother of Jared saw, even to the unfolding unto them all my revelations, saith Jesus Christ, the Son of God, the Father of the heavens and of the earth, and all things that in them are.
8 And he that will contend against the word of the Lord, let him be accursed; and he that shall deny these things, let him be accursed; for unto them will I show no greater things, saith Jesus Christ; for I am he who speaketh.
9 And at my command the heavens are opened and are shut; and at my word the earth shall shake; and at my command the inhabitants thereof shall pass away, even so as by fire.
10 And he that believeth not my words believeth not my disciples; and if it so be that I do not speak, judge ye; for ye shall know that it is I that speaketh, at the last day.
11 But he that believeth these things which I have spoken, him will I visit with the manifestations of my Spirit, and he shall know and bear record. For because of my Spirit he shall know that these things are true; for it persuadeth men to do good.
12 And whatsoever thing persuadeth men to do good is of me; for good cometh of none save it be of me. I am the same that leadeth men to all good; he that will not believe my words will not believe me—that I am; and he that will not believe me will not believe the Father who sent me. For behold, I am the Father, I am the light, and the life, and the truth of the world.
13 Come unto me, O ye Gentiles, and I will show unto you the greater things, the knowledge which is hid up because of unbelief.
14 Come unto me, O ye house of Israel, and it shall be made manifest unto you how great things the Father hath laid up for you, from the foundation of the world; and it hath not come unto you, because of unbelief.
15 Behold, when ye shall rend that veil of unbelief which doth cause you to remain in your awful state of wickedness, and hardness of heart, and blindness of mind, then shall the great and marvelous things which have been hid up from the foundation of the world from you—yea, when ye shall call upon the Father in my name, with a broken heart and a contrite spirit, then shall ye know that the Father hath remembered the covenant which he made unto your fathers, O house of Israel.
16 And then shall my revelations which I have caused to be written by my servant John be unfolded in the eyes of all the people. Remember, when ye see these things, ye shall know that the time is at hand that they shall be made manifest in very deed.
17 Therefore, when ye shall receive this record ye may know that the work of the Father has commenced upon all the face of the land.
18 Therefore, repent all ye ends of the earth, and come unto me, and believe in my gospel, and be baptized in my name; for he that believeth and is baptized shall be saved; but he that believeth not shall be damned; and signs shall follow them that believe in my name.
19 And blessed is he that is found faithful unto my name at the last day, for he shall be lifted up to dwell in the kingdom prepared for him from the foundation of the world. And behold it is I that hath spoken it. Amen.
We should seek after the meekness and humility of the brother of Jared. With a broken heart and a contrite spirit approach God; that we too may cry unto the Lord, rend the veil and be sanctified; that the Lord might show us the great and marvelous things shown unto the brother of Jared.
However, do we have the courage to ask the Lord to help us gain this attitude? Are we willing to submit to all the Lord may see needful to inflict upon us to get there?
For the natural man is an enemy to God, and has been from the fall of Adam, and will be, forever and ever, unless he yields to the enticings of the Holy Spirit, and putteth off the natural man and becometh a saint through the atonement of Christ the Lord, and becometh as a child, submissive, meek, humble, patient, full of love, willing to submit to all things which the Lord seeth fit to inflict upon him, even as a child doth submit to his father.
We should read, ponder and pray about these verses, and reflect upon them again and again about how they can help us make and maintain a connection with heaven.
