Love cannot be cold – for there is no such thing as cold love, but the love of which the Mother speaks in that passage1 is something very pure, fixed and constant; it does not leap like fire and sink for want of fuel, but is steady and all-embracing 
and self-existent like the light of the sun. There is also a divine love that is personal, but it is not like the ordinary personal human love dependent on any return from the person – it is personal but not egoistic,– it goes from the real being in the one to the real being in the other. But to find that, liberation from the ordinary human way of approach is necessary.
1 “It [the being] knows that this active state of love should be constant and impersonal, that is, absolutely independent of circumstances and persons, since it cannot and must not be concentrated upon any one thing in particular....” The Mother, «Prayers and Meditations», (Pondicherry: Sri Aurobindo Ashram, 2003), Collected Works of the Mother (second edition), vol. 1, p. 335.
