To understand Kṛṣṇa, you require your tongue. Generally we understand by seeing or by hearing. Hearing is there, but here it is recommended tongue, especially. Why tongue is used? Because if you simply chant Hare Kṛṣṇa by your tongue and taste Kṛṣṇa prasādam, you will understand Kṛṣṇa. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ. If you make it a promise that "I shall not talk anything except Kṛṣṇa's message," and if you promise that "I shall not take anything which is not offered to Kṛṣṇa," these two things, this prasādam and chanting, will make you perfect to understand Kṛṣṇa. In another place Kṛṣṇa says, mayy āsakta-manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ. This is yoga, bhakti-yoga. How easy it is. There are so many yogas, but if you practice bhakti-yoga you become first-class yogi.
- yoginām api sarveṣāṁ
- mad-gatenāntarātmanā
- śraddhāvān bhajate yo māṁ
- sa me yuktatamo mataḥ
- (BG 6.47)
So it is very easy, bhakti-yoga. It is not at all difficult. You haven't got to strain your body as in other haṭha-yoga practice you have to very undergo hardship, to sit in a particular posture, in a particular place. These things are stated in the Bhagavad-gītā. Not that you become yogi in a fashionable city as you'll find nowadays, yoga-āśrama signboard in a fashionable house, and you show some gymnastic, you become a yogi and get some money. Not that. This is bhakti-yoga, begins from jihva. Exercise your jihva, tongue; then you become a perfect yogi.
- mayy āsakta-manāḥ pārtha
- yogaṁ yuñjan mad-āśrayaḥ
- asaṁśayam samagram...
Samagram. Kṛṣṇa you understand fully, not partially. Not partially means not simply understanding impersonal Brahman. That is partial understanding. And then localized Paramātmā, that is also partial understanding. But when you understand Kṛṣṇa, the Supreme Person, that is full understanding. So you simply concentrate your mind unto the person of Kṛṣṇa, mayy āsakta-manāḥ. Here is Kṛṣṇa. We can see Kṛṣṇa. So if we simply concentrate our mind, meditation Sa vai manaḥ kṛṣṇa-padāravindayor vacāṁsi vaikuṇṭha-guṇānuvarṇane (SB 9.4.18). This was the practice done by Ambarīṣa Mahārāja.
