The psyche needs a psychology that gives it room to move. It requires careful but intuitive thinking to support its adventures and give them sufficient frameworks. Psyche and psychology too closely reflect each other to have the radical development of one without a corresponding theoretical radicalization of the other. Where they fail to keep pace, we call those psychic events for which our theory is inadequate, ‘alien’, placing them in patho- or para-psychology. Furthermore, we call radical theories (like those of Kundalini yoga) ‘mystical speculation’ when the poverty of our psychic life fails to produce the empirical data on which the psychological theories have been erected.
