Letters of Sri Aurobindo
Volume I - Part 5
Certainly, the subconscient is formed for this life only and is not carried with it by the soul from one life to another. The memory of past lives is not something that is active anywhere in the being – if by memory is meant the memory of details. That memory of details is quiescent and untraceable except in so far as certain constituent personalities taken over from the past retain the memories of the particular life in which they were manifest. E.g. if some personality that was put forth by one in Venice or Rome remembers from time to time a detail or details of what happened then. But usually it is only the essence of past lives that is activised in the being, not any particular memories. So it is impossible to say that the memory is located in a particular part of the consciousness or in a particular plane.
