Krishna consciousness means recognizing yourself as part of Krishna's body, serving the center joyfully.Listen — Srila Prabhupada Uvaca
Bhagavad-gītā 13.19 — October 13, 1973, Bombay 731013BG-BOMBAY [34:47 Minutes] Bg-13.19_731013BG-BOMBAY Prabhupāda: [aside:] So why don't you come forward? Back side, yes. So, svayaṁ bhagavān, Kṛṣṇa, kṛṣṇas tu bhagavān svayam [SB 1.3.28]. We have many times explained the word bhagavān.
Bhagavān means six opulences: riches and..., aiśvaryasya samagrasya vīryasya, potency; vīryasya yaśasaḥ, fame, reputation; aiśvaryasya samagrasya vīryasya yaśasaḥ śriyaḥ [Viṣṇu Purāṇa 6.5.47], beauty; jñāna, knowledge; and vairāgya, detachment. When one is full with all these six opulences, He's God. So people try to get the opulences. Everyone is trying by karma, jñāna, yoga.
But nobody can attain the opulences in full strength. That is not possible. So the simple definition of God is that one who is in full six opulences, He's God. That has been analyzed by great saintly persons, including Lord Brahmā, and it has been decided that the all the six opulences can be found in Kṛṣṇa.
Therefore, Brahmā's decree is given there in the Brahma-saṁhitā: īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ anādir ādir govindaḥ sarva-kāraṇa-kāraṇam [Bs. 5.1] In the Bhagavad-gītā also it is said, aham hi ādir devānāṁ maharṣīṇāṁ ca sarvaśaḥ [Bg. 10.2]. So that Supreme Personality of Kṛṣṇa is giving us knowledge, the ultimate goal of knowledge. And the living entities, their body, field of activities, in this Thirteenth Chapter they have been very thoroughly described, although Kṛṣṇa said it is summary. Because they cannot be described in full. This body, how many bodies you have changed?
Even in this life, we are changing our body. Every one of us, a little body of a child, then little grown-up body of a boy, then youthful body, then this old body. So as we are changing body, dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā tathā dehāntara-prāptiḥ [Bg. 2.13], similarly, after giving up this body, I will have to accept another body, and there are for 8,400,000 species of forms of body. According to our karma, we have to accept another body, karmaṇā daiva-netreṇa [SB 3.31.1], by superior arrangement. You cannot say that "I want this kind of body." God is not your order supplier.
You'll get. Either you ask for it or don't ask for it, you, according to your karma, you'll have a next body, karmaṇā daiva..., by the superior arrangement. If you work in this life like god, you'll get next life a god's body. And if you work in this life as a dog, then you get next the life as a dog.
That is not in your hands. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ [Bg. 3.27]. Guṇaiḥ, according to your qualities, as you will work, and prakṛti, nature, will give you a similar body. Otherwise, why do we find so many varieties of bodies? So many varieties.
