According to the Sanskrit dictionary Amara-kosa, sex life is also called gramya-dharma, material desire, but in spiritual life this gramya-dharma, the material desire for sex, is not very much appreciated. If one has a tinge of attachment for the material enjoyments of eating, sleeping, mating and defending, one is not niskincana. But one really should be niskincana. Therefore, one should be free from the desire to beget a child like Krsna by sexual enjoyment. This is indirectly hinted at in this verse.
