This is Kṛṣṇa consciousness. Upadhārya matiṁ kṛṣṇe (SB 2.4.1). So it is a great sacrifice. It is not like that, dharmārtha-kāma-mokṣa. No. It is above. People are generally become religious to get some material benefit, dharma artha. And as soon as he gets material benefit, he enjoys his senses, kāma. Dharma artha kāma. And when he fails to satisfy his senses, then he wants to become one with the Supreme. That's mokṣa.
So Kṛṣṇa consciousness is above these four principles, dharma, artha, kāma, mokṣa (SB 4.8.41, CC Adi 1.90). Kṛṣṇa consciousness is transcendental. Therefore one can give up, immediately. Just like sometimes Bharata Mahārāja, under whose name India is called Bhārata-varṣa, he also gave up.
He gave up his kingdom at the age of twenty-four years: young wife, young, nice children, big, whole empire. And it is said that he gave up everything just like one gives up his stool, evacuates, immediately goes away. So he gave up. So this is actually Kṛṣṇa consciousness, that we become completely free from any material possession. Any material possession.
It is very difficult, but just see, here Parīkṣit Mahārāja, due to his association with his spiritual master, Śukadeva Gosvāmī, he understood. He, according to his instruction, he gave his mind and everything to Kṛṣṇa, and he gave up the idea of enjoying his wife, children, palace, kingdom or animals, and so many things.
