Pradyumna: "Concentration of the mind upon Kṛṣṇa, the Supreme, is made possible by prescribed devotional service in nine different forms, of which śravaṇam is the first and most important."
Prabhupāda: So our yoga system is not like that, that we whole day, twenty-three hours and forty-five minutes, I engage myself in all nonsensical activities, and fifteen minutes I concentrate my mind, the meditation. That kind of yoga system is not here. Here, twenty-four-hours' meditation. Even during sleeping. Twenty-four hours means during sleeping also. Life should be melded, molded in such a way that twenty-four hours you'll be able to think of Kṛṣṇa. So we are engaging our students in so many Kṛṣṇa activities. They are going to the park, chanting Hare Kṛṣṇa, or distributing literature. All these activities, remembering Kṛṣṇa. They have no other, I mean to say, thought except Kṛṣṇa. So this fifteen minutes, twenty-minutes, sitting, is all right. But one who is twenty-four hours thinking of Kṛṣṇa or Viṣṇu, how far he is advanced, that can be imagined. Therefore Kṛṣṇa says personally, yoginām api sarveṣām: (BG 6.47) "Of all the yogis..."
There are different types of yogis. It is, it is not that... Just like we do some other business, twenty-three hours, forty-five minutes, and fifteen minutes we sit down for meditation. No. Twenty-four hours. Kīrtanīyaḥ sadā hariḥ. Sadā means twenty-four hours. That is recommendation of Caitanya Mahāprabhu.
- tṛṇād api sunīcena
- taror api sahiṣṇunā
- amāninā mānadena
- kīrtanīyaḥ sadā hariḥ
- (CC Adi 17.31)
To execute this twenty-four-hours' meditation one has to be, become, has to become, has to become very humble. Because so many people will criticize. Just like last night our Ātreya Ṛṣi was speaking that some of his fellow officer was criticizing him. So we have to tolerate. Just like when the elephant passes, many dogs bark. So we do not care for these dogs barking. As elephant, we must go on gravely. You see.
Therefore tṛṇād api sunīcena taror api sahiṣṇunā. We have to execute this twenty-four-hours' Kṛṣṇa business, Kṛṣṇa consciousness, always absorbed in thought of Kṛṣṇa—in sitting, in walking, in eating, in sleeping, everything. In working. That is first-class yoga. It is also yoga, but first-class yoga. Not third-class, fourth-class yoga. Of course, any yoga system, we cannot say it is third class, fourth class, but when we make comparative study, there must be something better or something inferior. Just like we have already described. You have got a staircase to go to the one hundredth floor. So one has gone twenty steps, one has gone fifty steps, one has gone seventy-five steps, one has gone full hundred steps. So one who has gone twenty-five steps, he cannot be compared with one who has gone one hundred steps. Similarly, the yoga system is just like a staircase for going to the spiritual world. So one who has taken to Kṛṣṇa consciousness, he's on the top, topmost yoga system. Go on.
