There are nine processes. So keep yourself always engaged in either of these nine processes. That is twenty-four hours' engagement. Satatam. Teṣāṁ satata-yuktānām (BG 10.10): one who is always engaged in Kṛṣṇa's service. How? Bhajatāṁ prīti-pūrvakam. Not that it is disgusting. No. Prīti, with love. Of course, it may be disgusting in the beginning. But as you make progress in service, you'll find it pleasing, not disgusting. That is the taste that you have developed. When you do not feel disgusted in the service, in executing the service of the Lord, that means you have made progress. In the material service becomes disgusting.
Just like, for example, here is Kṛṣṇa's name, "Hare Kṛṣṇa." Throughout one's life, twenty-four hours, he's chanting Hare Kṛṣṇa. But it is not disgusting. But take any material name and chant it three times, you become disgusted. This is a fact. But these boys, these girls, throughout . . . throughout their life will go on chanting Hare Kṛṣṇa, will never be disgusted, but they will chant more and more. So this is prīti. The more you chant, the more you become attached: "Let me chant more." Not disgusted, but "Let me chant more." This is called prīti.
Similarly, any service of the Lord. This is service by śravaṇam and kīrtanam. That is the beginning. Śravaṇaṁ kīrtanaṁ viṣṇoḥ smaraṇa (SB 7.5.23): then always remembering Kṛṣṇa. When you are perfect in chanting and hearing, then you'll always remember Kṛṣṇa. That means in the third stage you become the greatest yogī. Because Kṛṣṇa says, yoginām api sarveṣāṁ mad-gatenāntar-ātmanā śraddhāvān bhajate yo mām
