"Occult knowledge without spiritual discipline is a dangerous instrument, for the me who uses it as for others, if it falls into impure hands. Spiritual knowledge without occult science lacks precision and certainty in its objective results; it is all-powerful only in the objective world. The two, when combined in inner or outer action, are irresistible and are fit instruments for the manifestation of the supramental power. "

Mirra Alfassa (Mother)
