Bhagavad-gita As It Is Lectures

Lecture on BG 2.12 -- Mexico, February 12, 1975:

So Kṛṣṇa says, the supreme authority says, mad-yājino 'pi yānti mām (BG 9.25). If somebody cultivates Kṛṣṇa consciousness, he can go there. It is not difficult; simply you have to change your mode of life. To become Kṛṣṇa conscious means to be pure in the original spiritual existence. We are pure as Brahman, as spirit soul, but because we have contaminated these material modes of nature, our consciousness is now different. So on account of different consciousness, there are three classes of men. One class of men is very intelligent; one class of men, very passionate; and one class of men, fools and rascals. So in order to understand your promotion to the spiritual world, you have to become first-class man. First-class man means brāhmaṇa. A brāhmaṇa means he is truthful, he is self-controlled, he is simple, he is tolerant... In this way there are nine qualification to become first-class man. And to become first-class man, the preliminary qualification is that you should not become sinful.
