Here it is said that viṣayā vinivartante. One may be refraining from enjoying materially by somehow or other, by force . . . nirāhārasya dehinaḥ, rasa-varjaṁ raso 'py asya paraṁ dṛṣṭvā nivartate. But one who is spiritually advanced, he is not forced. He is voluntarily giving up. That is the difference. Voluntarily giving up. How? Why voluntarily giving up? Now, paraṁ dṛṣṭvā nivartate. He has found something sublime, so sublime that he doesn't care for material enjoyment. He is not forced. He voluntarily gives up. That is the criterion of spiritual life. There is no force.
Just like there is a nice verse given by Yamunācārya. Yamunācārya, he was a great emperor, but later on, he became a great devotee of the Lord under the disciplic succession. Now, he has got very nice verses written by him. One of the verses is stated like this:
- yad-avadhi mama cetaḥ kṛṣṇa-padāravinde
- nava-nava-dhāmany udyataṁ rantum āsīt
- tad-avadhi bata nārī-saṅgame smaryamāne
- bhavati mukha-vikāraḥ suṣṭhu niṣṭhīvanaṁ ca
- (Śrī Yāmunācārya)
He says, the experience of his life . . . so he was a king. He enjoyed his life like anything. Now, after he became a great devotee, spiritually engaged, he expresses his . . . that experience in this way, that yad-avadhi mama cetaḥ kṛṣṇa-padāravinde: "Since I have engaged my heart and soul in the supreme devotional service of the Lord, since then . . ." What is the result? Yad-avadhi mama cetaḥ kṛṣṇa-padāravinde nava-nava-rasa-dhāmany udyataṁ rantum āsīt: "I am getting every moment a new type of transcendental pleasure. Since then . . ." Bata nārī-saṅgame. This is materially. Nārī-saṅga means sex life, combination of man and woman, nārī-saṅgame. He says that "Since then, that whenever I think of sex life . . ." Because he has experienced. He was a family man, he was a king. He said that "Whenever I think of, not to act, but whenever I think of sex life, oh, I say, now, 'tuh!' ".
