The transmigration of the soul into another body, however, is restricted to three times; and if two souls in their third residence in human bodies are still too weak to resist all earthly trammels and to acquire the necessary experience, they are both united and sent into one body, so that they may be able conjointly to learn that which they were too feeble to do separately. It sometimes, however, happens that it is the singleness and isolation of the soul which is the source of her weakness, and she requires help to pass through her probation. In that case she chooses for a companion a soul which has more strength and better fortune. The stronger of the two then becomes as it were the mother; she carries the sickly one in her bosom, and nurses her from her own substance, just as a woman nurses her child. Such an association is therefore called pregnancy (‏עיבור‎), because the stronger soul gives as it were life and substance to the weaker companion. [23] As the world, like all other living beings, is a further expansion of the Deity’s own substance, it too must ultimately share that blessedness which it enjoyed in its first evolution. This is indicated in the letter ‏ב‎ with which the history of the creation begins (i.e. ‏ב״ראשית‎), and which is also the first letter in the word blessing (‏ב״רכה‎). [24] Even the archangel of wickedness, or the venomous beast (‏חוייא בישא‎), or Samäel (‏סמאל‎), as he is called, will be restored to his angelic nature and name, inasmuch as he too, like all other beings, proceeded from the same infinite source of all things. The first part of his name (‏סﬦ‎), which signifies venom, will then be dropped, and he will retain the second part (‏אל‎), which is the common name of all the angels. This, however, will only take place at the advent of Messiah. But his coming is retarded by the very few new souls which enter into the world; as many of the old souls which have already inhabited bodies have to reenter those bodies which are now born, in consequence of having polluted themselves in their previous bodily existence, and the soul of the Messiah, which, like other souls, has its pre-existence in the world of the Sephiroth, cannot be born till all human souls have passed through their period of probation on this earth, because it is to be the last born one at the end of days. Then the great Jubilee year will commence, when the whole pleroma of souls (‏אוצר הנשמות‎), cleaned and purified shall return into the bosom of the Infinite Source; and they shall be in “the Palace which is situate in the secret and most elevated part of heaven, and which is called the Palace of Love (‏היכל אהבה‎). There the profoundest mysteries are; there dwells the Heavenly King, blessed be he, with the holy souls, and is united with them by a loving kiss. (Sohar, ii, 97 a.) “This kiss is the union of the soul with the substance from which it emanated.” (Ibid., i, 168 a.) Then hell shall disappear; there shall be no more
