Emanations of The Mother

In a sense the four Powers of the Mother may be called, because of their origin, her Emanations, just as the Gods may be called Emanations of the Divine, but they have a more permanent and fixed character; they are at once independent beings allowed their play by the Ady¯a Shakti and yet portions of the Mother, the Mahashakti, and she can always either manifest through them as separate beings or draw them together as her own various Personalities and hold them in herself, sometimes drawn back, sometimes at play, according to her will. In the supramental plane they are always in her and do not act independently but as intimate portions of the original Mahashakti and in close union and harmony with each other.
