If you want to make your life so perfect, not to go through this process of birth, death, old age and disease, you can do that. There is process. But if we neglect, that is our business. But the śāstra, the knowledge, the Vedas, the big, big ācāryas, Kṛṣṇa, His incarnation, His devotees—they are simply trying to give you this knowledge that you can make your life perfect: no more death, no more birth, no more old age, no more disease. That you can make. That is possible.
Therefore śāstra says that gurur na sa syāj jananī na sā syāt pitā na sa syāt (SB 5.5.18), in this way, that na mocayed yaḥ samupeta-mṛtyum. This is the perfect knowledge, perfection of life. Samupeta-mṛtyum. We have got a situation in this material world, repetition of birth, death, old age and disease. But śāstra says, "One should not become a guru, one should not become a father, one should not become a mother, one should not become a relative, one should not become a friend," in this way, he says, "if one cannot give relief to his friend or son or disciple, relief from the impending birth, death, old age and disease." This is real contraceptive method. If you think that "If a child is born, I shall educate him in such a way that this birth will be his last birth. Next he is going to back to home, back to Godhead," then produce a child. Otherwise don't produce. This is spiritual contraceptive. This is real father and mother. Otherwise a dog is also becoming a father. (laughter) The such kind of father-becoming is not recommended in the Vedic civilization. Just become a real father to give the real benefit to the son. Then you become a father. This is called varṇāśrama-dharma
