Three Things

It is necessary to lay stress on three things:

(1) an entire quietness and calm of the mind and the whole being.

(2) a continuance of the movement of purification described in the Post Scriptum so that the psychic being (the soul) may govern the whole nature.

(3) the maintenance in all conditions and through all experiences of the attitude of adoration and bhakti for the Mother.

These are the conditions in which one can grow through all experiences with security and have the right development of the complete realisation without disturbance to the system or being carried away by the intensity of the experiences. Calm, psychic purity, bhakti and spiritual humility before the Divine are the three conditions. The experiences in themselves are right and helpful.
