The soul impressed deeply in the world of the jinns by some personality coming back from the earth, an impression deeply engraved upon that soul which it can never throw away, certainly becomes that personality with which it is impressed. Suppose a soul is impressed in the world of the jinn with the personality of Beethoven; when born on earth he is Beethoven in thought, feeling, tendency, inclination and knowledge. Only in addition to that personality he has the heritage of his parents and of his ancestors. As the son of a certain family .is called by the name of that family, so the impression of a certain personality may rightfully be called by that name. Therefore if Shankaracharya claims to be the reincarnation of Krishna, there is every reason for his claim, and this theory stands in support of it. Life from the beginning to the end is a mystery. The deeper one dives in order to investigate the truth the more difficulty one finds in distinguishing what is called individuality. But it is not the aim of the wise to hold on to individuality. Wisdom lies in understanding the secret of individuality, its composition or its decomposition, which resolves in the end into one individuality, the individuality of God. As it is written, "There is one God; none exists save He.'
