Krishna reveals Himself only to devoted servants through humble practice, not to intellectual speculators.Listen — Srila Prabhupada Uvaca
Bhagavad-gītā 7.1 — March 26, 1968, San Francisco 680326BG-SAN FRANCISCO [39:15 Minutes] Prabhupāda: mayy āsakta-manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ asaṁśayaṁ samagraṁ māṁ yathā jñāsyasi tac chṛṇu [Bg. 7.1] [Now hear, O son of Pṛthā [Arjuna], how by practicing yoga in full consciousness of Me, with mind attached to Me, you can know Me in full, free from doubt.] So Kṛṣṇa is describing personally. Kṛṣṇa's name is Yogeśvara, and Lord Śiva's name is Yogīśvara. Yogeśvara means... Yoga, the connecting link between the soul and the Supersoul, or the Supreme and the minute living creatures—that is called yoga.
Connecting. So the... Who is the Supreme Personality of Godhead? Yogeśvara.
The ultimate object of yoga is Kṛṣṇa. Therefore Kṛṣṇa's name is Yogeśvara. Yatra yogeśvaraḥ hariḥ. At the conclusion of the Bhagavad-gītā it is said by Sañjaya, yatra yogeśvaraḥ hariḥ [Bg. 18.78]. [Wherever there is Kṛṣṇa, the master of all mystics, and wherever there is Arjuna, the supreme archer, there will also certainly be opulence, victory, extraordinary power, and morality. That is my opinion.] The place where Yogeśvara, the supreme master of all yoga systems, Kṛṣṇa, is there... And yatra pārtho dhanañjaya, and where there is Arjuna, the greatest fighter, there is undoubtedly victory there. Because Bhagavad-gītā was spoken... The narration which we are reading, it is the description of Sañjaya as secretary of Mahārāja Dhṛtarāṣṭra. Just like running from a radio.
The play is going on in the auditorium, but you can hear from the room. Just like we have got now mechanical arrangement, similarly, at that time, maybe the same arrangement, but there was no machine. Still, the secretary of Dhṛtarāṣṭra could see what was going on in the battlefield, and he was just narrating to Mahārāja Dhṛtarāṣṭra, who was blind. In other sense it may be said that there was television, and Dhṛtarāṣṭra, being blind, he could not see, and Sañjaya, his secretary, was explaining what was seen in the television. But this is the position. Anyway, so the conclusion made by Sañjaya was this, yatra yogeśvaraḥ hariḥ [Bg. 18.78]. Hari means the Supreme Personality of Godhead.
The side in which the Yogeśvara, Kṛṣṇa... My point is that Kṛṣṇa's name is Yogeśvara. Nobody can be better yogī than, or the master of yoga. There are different systems of yoga, and Kṛṣṇa is the master of yoga. And Lord Śiva is called Yogīśvara.
There are many different kinds of yogīs. Yoga means the system, and the yogī means the person who practices the system. So the object of yoga, ultimate goal of yoga, is to understand Kṛṣṇa. Therefore Kṛṣṇa consciousness means to practice the topmost type of yoga system. So this yoga system is being described by Kṛṣṇa Himself.
Why? Because He was teaching His most intimate friend, Arjuna. Vyākhyāta-lakṣaṇe svopasye mayy āsakta-mati-mātra vyākhyāta-lakṣaṇe svopasye saḥ. Now in the beginning, the Lord says that "This system of yoga can be practiced by persons who have developed attachment for Me." This attachment I have described for the last three, four days in a different way.
