Sweet Mother, can one realise the Divine through love alone?
Oh! yes, my child, certainly. It is even the most direct way.
One can realise the Divine, that is to say, identify oneself with the Divine, become fully conscious of the Divine and be an instrument of the Divine. But naturally, one does not realise the integral yoga, for it is only along one line. But from the point of view of identification with the Divine it is even the most direct path.
