In plain words
With effort one may press oil from sand; going about, one may come by a hare's horn; but without bhajan none can attain parā-bhakti; without knowing the Truth none can cross the ocean of birth.
So only those who have attained the principle of Prema can cross this ocean of birth. So the chief path is to offer our all to God and to seek the Ānanda of His Prema.
A small example. The moment a maiden is married, she leaves all that she held to be her everything: the mother who bore her, reared her and brought her up, the father who fed her, raised her and gave her in marriage, the sisters born with her, elder and younger, and the brothers; and she goes with a new person, in full faith, wherever he goes. She does not hanker in the least for the comforts and riches of her own home. In the same way, once the nature of our mind has been offered to God, one's mind, one's wealth, one's honour, one's feeling, one's Prema: all of it is offered up to God. That, they said, is true ananya Bhakti.
God is the sun of Jñāna
Unless one thing is given up, one is not fit to receive another. Only when we offer up the unrest in us does equality grow in us. Only when hatred is given up does Prema arise in us. There is no chance at all of gaining one thing unless we give up another. Only when we go to a shop and hand the shopkeeper ten rupees will he toss a handkerchief in our face. Only when you pay the price due for each article does that article become yours. It comes into your hands. Without paying in this way, without giving in this way, can the supremely sacred principle of Prema be had? At times God gives suffering to many people in many ways, to bring them onto the sacred and higher path. He sends troubles.
