One whose heart is too much engrossed with tamo-guṇa, rajo-guṇa, they are lower grade, pāpa-yoni. And gradually, one who is free from the tamo-guṇa, rajo-guṇa . . . even sattva-guṇa. Of course, sattva-guṇa is taken the platform of goodness. That is the only hope in this material world, that one has to come by endeavor to the sattva-guṇa platform. Then the heart disease, kāma . . . hṛd-roga-kāma. It is a heart disease. Kāma means lusty desires simply to enjoy senses. This is called kāma. Hṛd-roga-kāma āpṛṇoti.
So the Kṛṣṇa consciousness movement means to cure the heart disease full with lusty desires. This is Kṛṣṇa consciousness. And the perfection comes when anyābhilāṣitā-śūnyaṁ (Brs. 1.1.11)—no more any material desire. That is possible. Yaṁ labdhvā cāparaṁ lābhaṁ manyate nādhikaṁ tataḥ (BG 6.22). If you get something, that something, yaṁ labdhvā cāparaṁ lābhaṁ, you are full satisfied that, "I don't want anything more." Svāmin kṛtārtho 'smi varaṁ na yāce (CC Madhya 22.42), Dhruva Mahārāja said. He went to the forest to undergo severe austerities so that he can see Nārāyaṇa and beg some benefit, to get a greater kingdom than his father. He was insulted by his stepmother, so the boy, son of a kṣatriya, he determined that, "I shall have a better kingdom than my father." So he got it. By Kṛṣṇa's grace he got it, that Dhruvaloka, the polestar. It is very big star. So he went for this purpose. Arthārthī. Catur-vidhā bhajante māṁ sukṛtino arjuna (BG 7.16). Arthārthī. Ārto arthārthī. So he was in search after money, Dhruva Mahārāja, and therefore at five years old he went to the forest. His mother advised that, "Kṛṣṇa can help you only." Others cannot help.
