The mind retains the gathered experience of male and female incarnations. Since the soul identifies itself with the body, the psychological tendencies that harmonize with the sex of the body find a suitable medium for expression. The tendencies that are characteristic of the opposite sex are ordinarily suppressed into the unconscious part of the mind because they do not harmonize with the sex of the body and find the medium of expression obstructive. When the soul takes a female body, the male tendencies are, so to speak, held in abeyance; and only the female tendencies are released for expression. In the same way, when the soul takes a male body, the female tendencies are held in abeyance; and the male tendencies are released for expression.
