We may mention here en passant what Sri Aurobindo wrote to Motilal Roy sometime in the middle of 1913. “Tantric Yoga is not yet of the first importance for us, the perfection of the basis of Vedanta is the one thing supremely important; for that cannot be perfect until this has been developed at least to a certain point.” Sri Aurobindo’s “not yet” is significant. His own focus was on Vedic-spiritual approach: His was the Purusha Yoga. But it is also true that control over the occult gives a definite precision to the spiritual. While the Mother herself acquired those siddhis of the occult in the earlier phase, her own approach was towards the psychic coming forward and taking charge of the sadhana. Later, in the deeper context of the physical transformation, the luminous occult had to be dealt with when the spiritual siddhi could provide the needed support or ādhāra. Ultimately it is the Shakti who is going to do the alchemic miracle of the physical transformation; it is her work. She has to be allowed to work in us. That indeed is the entire thrust of the sadhana.
