So our, this Kṛṣṇa consciousness movement is meant for understanding the Absolute Truth in complete, without any doubt, and without any incompleteness. This is also confirmed in the Eighteenth Chapter, that if you want to know God in completeness and without any doubt, then you have to take to bhakti-yoga process. It is said,
- bhaktyā mām abhijānāti
- yāvān yaś cāsmi tattvataḥ
- tato māṁ tattvato jñātvā
- viśate tad-anantaram
- (BG 18.55)
The meaning is that "One can understand Me only by this bhakti-yoga process. And when one is fully aware of the Supreme Personality of Godhead, then he becomes fit to enter into the Kingdom of God." So the purpose of yoga practice is to promote or to leave this material atmosphere and enter into the spiritual atmosphere. All the yogis, the jñāna-yogī, they remain in the impersonal feature of the Absolute Truth. The dhyāna-yogī is practicing the localized aspect, but the bhakti-yogī, he is promoted directly in the planet which is called Goloka Vṛndāvana, and there he associates with the Supreme Personality of Godhead and enjoys life blissfully, eternally.
So there are different planetary systems within this material world. Just like we are situated, it is called Bhūrloka. Above this, there is Bhuvarloka. Above that, there is Svarloka, there is Janaloka, there is Maharloka, Satyaloka. In this way, there are seven steps of planetary systems up, and similarly, seven planetary systems down. So by jñāna-yoga, by bhakti-yoga, dhyāna-yoga, means mystic yoga system, we can be promoted to the higher system, but if you practice the bhakti-yoga, then you go to the transcendental world directly and associate with the Supreme Personality of Godhead. The dhyāna-yogī and jñāna-yogī can also go to the Brahmaloka or brahma-jyotir, but there is chance of falling down again to this material world. But generally, jñāna-yogī remains a speculator within this material world, and dhyāna-yogī, they, as soon as they get some material miracle power, they become implicated with this power, no more going to the spiritual world. But bhakti-yogī, being perfectly the yogi, the topmost yogi, he can enter the kingdom of God, or the planet where God is there. God is everywhere, but He has got a special planet, which is called Goloka Vṛndāvana. You can enter there and mix with the Supreme Lord just like we are here, mixing one another. I can see you, you can see me, similarly, you can go directly, see God and live with Him, dance with Him, play with Him, eat with Him. That is the perfection of life.
This perfection of yoga can be achieved by practicing bhakti-yoga as it is recommended here: mayy āsakta-manāḥ pārtha yogaṁ yuñjan mad-āśrayaḥ, under the guidance of the Supreme Personality of Godhead or His representative, bona fide. If you practice this yoga, then you can understand the Supreme Personality of Godhead in complete, without any doubt. And if you practice this yoga in this life, and try to understand Kṛṣṇa, what He is, then, after giving up this body—you have to give up this body, today or tomorrow—then you go directly to Kṛṣṇa. It is therefore explained in the Fourth Chapter, janma karma me divyaṁ yo jānāti tattvataḥ punar janma naiti mām eti kaunteya (BG 4.9). "My dear Arjuna, anyone, if he simply tries to understand why I come in this material world, what is My mission, what do I do, if he simply one understands, then he immediately becomes fit for being transferred to the spiritual world." So our Kṛṣṇa consciousness movement is to educate people how to understand Kṛṣṇa, and then make his life perfect.
