Continuing, he (Sri Ramakrishna) said: "Longing is like the rosy dawn. After the dawn out comes the sun. Longing is followed by the vision of God".
"God reveals Himself to a devotee who feels drawn to Him by the combined force of these three attractions: the attraction of worldly possessions for the worldly man, the child's attraction for its mother, and the husband's attraction for the chaste wife. If one feels drawn to Him by the combined force of these three attractions, then through it one can attain Him.
"The point is, to love God even as the mother loves her child, the chaste wife her husband, and the worldly man his wealth. Add together these three forces of love, these three powers of attraction, and give it all to God. Then you will certainly see Him.
"It is necessary to pray to Him with a longing heart. The kitten knows only how to call its mother, crying, 'Mew, mew!' It remains satisfied wherever its mother puts it. And the mother cat puts the kitten sometimes in the kitchen, sometimes on the floor, and sometimes on the bed. When it suffers it cries only, 'Mew, mew!' That's all it knows. But as soon as the mother hears this cry, wherever she may be, she comes to the kitten."
