Another explained the verse: "And from my flesh, I shall see G-d," (Iyov, 19:26.) What is the meaning of "And from my flesh?" It would be more proper to say, "from my inner essence." However, "my flesh" is to be understood literally (as being the place of the Brit,) as in the verse, "and the holy flesh is removed from thee," (Yirmeyahu, 11:15,) and also, "and my Brit shall be in your flesh," (Bereshit, 17:13.)
For thus we have learned: Whenever a man is stamped with the holy impress of this sign, through it literally he will attain his awareness of G-d, because the holy soul is attached to this place (in the parallel spiritual world of the Yesod.)
But if he does not merit this, because he did not guard this sign, then of him it is written, "They lose the soul of G-d," (Iyov, 4:9,) for he did not properly guard the impress of G-d. If, however, he guards it, then the Shechinah does not part from him....
When is the Shechinah established with him? When he is married, then the sign enters into its intended place....The holy soul is attached to this place, and everything depends on this sign. Thus it is written, "And from my flesh, I shall see G-d." This is the perfection of everything, literally from "my flesh," from this very sign. Therefore, how fortunate are the holy Jewish People who are attached to the Holy One, Blessed Be He; fortunate are they in this world and fortunate in the world to come. Regarding them it is written: "But you who cleave to the L-rd your G-d, are alive every one of you this day," (Devarim, 4:4.)
