"It is astonishing to what a degree some remember instances from their past lives, whereas others have completely lost all memories of their former accumulations. A karmic cause does not completely explain such a marked difference in the understanding of life. Truly, the deciding factor in such understanding lies not in the circumstances of former lives, but in the acceptance of Agni. People call such wisdom a talent, but it is no special talent to keep Agni alight. Only the kindling of the centers produces uninterrupted vigilance of consciousness. Even a partial manifestation of Agni already preserves the accumulations inviolate. Agni is no violator, but our friend. It must be explained that the ascent of the spirit is indeed a manifestation of Agni."
