Receptivity is one of the twelve attributes of the Mother.
Receptivity—the power to receive the Divine Force and to feel its presence and the presence of the Mother in it and allow it to work, guiding one’s sight and will and action. If this power and presence can be felt and this plasticity made the habit of the consciousness in action,—but plasticity to the Divine Force alone without bringing in any foreign element,—the eventual result is sure.
Sri Aurobindo – Letters on Yoga – II : CWSA, Vol. 29, p. 266
Receptivity is the capacity of admitting and retaining the Divine Workings.
Receptivity: conscious of the Divine Will and surrendered to it.
Integral receptivity: the whole being is aware of the Divine Will and obeys it.
Psychic receptivity: the psychic responds joyously to the ascending force.
Mental receptivity: always ready to learn.
Emotional receptivity: emotions wanting to be divinised.
Vital receptivity happens only when the vital understands that it must be transformed.
The vital blossoms in aspiration for the Divine.
Physical receptivity: that which one should not have except towards the Divine.
Supramentalised receptivity: the receptivity of tomorrow.
