If you love children for making them Krsna conscious, then it is loving Krsna. Krsna wants sarva-dharman parityajya mam ekam saranam vraja [Bg. 18.66]. So if you help… What is our movement? Why I have come to your country? Because to make you Krsna conscious. So there is love of Krsna. Otherwise why…, what is the business, I have come to you? I have no business. Because I love Krsna, I want to see all, everybody in the world, to become Krsna conscious. Otherwise why in this old age we are trying so much?
Similarly, if you love your children to make them Krsna conscious, then produce hundreds of children and make them. That is love of Krsna. And if you make them cats and dogs, then one children producing is also sinful. That is also sinful. But if you can make them Krsna conscious, then produce hundreds of children. That is Krsna's love. The Bhagavata says, pita na sa syaj janani na sa syat: "One should not become father, one should not become mother…" na mocayed yah samupeta-mrtyum [SB 5.5.18], "…if he cannot deliver the children from the imminent hands of death." That is the condition. So if you cannot make…
Death cannot be avoided unless one becomes Krsna conscious. So if you cannot make your children Krsna conscious and stop their death, birth and death process, then don't become a father. This is the injunction. And if you can actually do that, then become father of hundreds children. This is the condition. If you cannot make your children… If you can make, that is love of Krsna.
Because unless you love Krsna, why you should be interested to make others Krsna conscious? Let them go to hell. Why you should be so much working hard to make them Krsna conscious, unless you love Krsna? This is the sign of love. "I love Krsna, but I do nothing for Krsna," that is nonsense. That is nonsense. Therefore I said that our Guru Maharaja's brother, he criticizes Guru Maharaja, but what he has done for Krsna? And what my Guru Maharaja has done? Unless my Guru Maharaja had produced me, how this Krsna consciousness
movement is going all over the world? And what he has done? Simply criticizing is no use. We want to see practical. Do you understand or not?
