The Masters of Wisdom, in one of their letters known as ” Devachan Letter”, give an inspired definition of both Personality and Individuality:
“ (1) The Paccika Yana —(in sanskrit “Pratyeka”) means literally— the “personal vehicle” or personal Ego, a combination of the five lower principles. While—
(2)The Amita Yana- (in sanskrit “Amrita”) is translated :— the “immortal vehicle” or the Individuality, the Spiritual Soul, or the Immortal monad— a combination of the fifth, sixth and seventh.”
Both Personality and Individuality constitute Man in his mortal and immortal essence.
