In plain words
You do not know the happiness in these hardships. Only I know it. Only because I suffered so many hardships am I able to be in Your presence without a break. All my sons have become worthy of Your grace. That alone is my joy. Without such joy, however many sons are born, what use is it?
“The undiscerning, deluded about life, weep that no sons are born to them; were not many sons born to the lord of the Kauravas? Through them, what end did he reach? Did any evil fate befall Śuka, who had no sons? Is the state of liberation lost to one who has no son?”
There is no joy that comes from sons being born, and if they are not, no loss comes of it. Sons, being born, must bring a good name. They must live in good conduct. They must join good company. All my sons have reached God's presence. All of them, from rising at dawn until lying down at night, ‘Kṛṣṇa! Kṛṣṇa!’ they kept remembering. That alone is my joy; make it so that such joy is ever mine,” she prayed. But do mothers today ask like this? They do not. The son must be well, of course. But they do not wish that he reach God's presence. ‘If he goes to God's presence, what will become of my son!’ they fear. Reaching God's presence alone is needed. If one does not reach it but sits somewhere else, what use is that? Being born, one must reach the very place one is to reach.
Whatever hold you have taken, you have truly taken it; stay just so till the hold wins through; whatever you have desired, you have truly desired it; keep worshipping till the desire is fulfilled; whatever you have asked, you have truly asked it; do not let go till what you asked is given; whatever you have thought of, you have truly thought of it; do not move away till the thought comes true: either I, unable to bear the pleading, must come to the rescue, or you, forgetting the body, must go on asking; but to stop halfway and turn back is no devotee's vow.
