In diseased state, if we imitate a healthy man's activity, then death is sure. Death is sure. Nobody can say: "Oh, Kṛṣṇa enjoyed with so many girls. Oh, let me enjoy also." You cannot, because you are in diseased condition. If you do that, then you continue your diseased life and you'll die.
So for us, so long we are conditioned by this material nature, we have to live under regulation, under restriction. And as soon as we are free from this material entanglement, when we come to Kṛṣṇa consciousness fully, even in perfection of Kṛṣṇa consciousness here, you'll have that transcendental nature. Just like several times I have cited one śloka from Yamunācārya. Yamunācārya was a great king and later on, he became a great devotee.
He has written his life's experience in one verse. Yad-avadhi mama cetaḥ kṛṣṇa-padāravindayor: "So long my mind and attention is absorbed in Kṛṣṇa consciousness," tadavadhi, "since then," tad-avadhi bata nārī-saṅgame (Yamunācārya) "sex life, as soon as I remember about that, it becomes very nasty thing for me." This is the experience. And in the Śrīmad-Bhāgavatam also . . . sex life is there in Kṛṣṇa, not exactly like this, but there is a, I mean to say, unification or embracing, kissing, everything is there, but there is no pregnancy, there is no abortion. That is the perfection.
