Madhudviṣa: He wants to know how in the beginning, when we are starting to engage in Kṛṣṇa consciousness, devotional service to God, can you develop enthusiasm and sincerity.
Prabhupāda: Yes. The thing is if you want to become a drunkard, you mix with the people who drinks. Then you drink little, little, little. Then you become a big drunkard. Similarly, if you have got little sense that "I shall understand what is God," this very much qualification, if anyone only wants sincerely that "I will understand what is God," then your drinking business begins immediately. (break)
Then if you continue, then as the drunkard becomes big drunkard, you become a big devotee. The beginning is that you must be little anxious that how I can understand God. This is the qualification, that's all. And if you are serious, then God is within you, He will give you intelligence. That is stated in the Bhagavad-gītā. Teṣāṁ nityābhiyuktānāṁ bhajatāṁ prīti-pūrvakaṁ buddhi-yogaṁ dadāmi tam. When God sees that you are sincere, He is within you, He will dictate you do like this, you do like this, and you will make advance.
