Now this Kṛṣṇa consciousness movement is meant for creating some brāhmaṇas, or the most intelligent class of men. There is no hindrance. Anyone can become brāhmaṇa. Just like in education anyone can become engineer, anyone can become medical practitioner or anyone can become lawyer if he takes such education from the very beginning, similarly, brāhmaṇa, kṣatriya, vaiśya, śūdra, there are natural division of the society. But at the present moment there is scarcity of brāhmaṇa. Brāhmaṇa means who has got very nice intellectual brain, who can understand the Absolute Truth. He is called brāhmaṇa. So this Kṛṣṇa consciousness movement is trying to create some good brains so that he can understand, one can understand what is the Absolute Truth. This is the movement.
So here the same instruction is there in the Bhagavad-gītā, which is spoken by Kṛṣṇa, the Supreme Personality of Godhead. So when Arjuna was perplexed whether to fight or not to fight, he was very much perplexed, and he accepted Kṛṣṇa as his spiritual master. Śiṣyas te 'haṁ śādhi māṁ prapannam (BG 2.7):
(Now I am confused about my duty and have lost all composure because of weakness. In this condition I am asking You to tell me clearly what is best for me. Now I am Your disciple, and a soul surrendered unto You. Please instruct me.)
"My dear Kṛṣṇa, just now we are talking like friends, but this is a very important factor. I have to decide. Now I accept You as my spiritual master, and You give me the right guidance." The whole transaction of the Bhagavad-gītā is based on the talking of Kṛṣṇa and Arjuna only.
