This is the competition between Kṛṣṇa and His devotee. Kṛṣṇa wants to give everything to the devotee. He wants to see that "My devotee is very comfortable." Just like the father wants to see the children are very comfortable. So why the devotees should be hankering after something material? No. Kasmād bhajanti kavayo dhana-durmadāndhān (S.B.2:2:5). Śukadeva Gosvāmī said. Why we should go to the puffed-up rich men for begging something? Kṛṣṇa will arrange for everything. My Guru Mahārāja used to say that "You do not try to preach for getting some money. Money will come automatically. On your feet money will say, 'Please accept me.' " You should preach very sincerely. That is your business. Never bother that "Where is money? Where is money, money, money?" Money... Muktir mukulitāñjaliḥ sevate asmān dharmārtha-kāma samaya pratīkṣāḥ. This is a statement of Bilvamaṅgala Ṭhākura.

Similarly, the devotional service, we have to execute with patience, with enthusiasm. Utsāhāt dhairyāt niścayāt tat-tat-karma-pravartanāt. We must be enthusiastic that we... "I shall engage myself very nicely in Kṛṣṇa consciousness movement." That is first qualification, enthusiastic. Dullness will not help you. You must be very enthusiastic. My Guru Mahārāja used to say, prāṇa ache yara sei hetu pracāra. A preacher can, a person can become a preacher if he has got life. A dead man cannot become a preacher. So you must be very enthusiastic that "I shall preach the glories of the Lord to my best capacity." It is not that one has to become very learned scholar to become a preacher. Simply it requires enthusiasm, "My Lord is so great, so kind, so beautiful, so wonderful. So I must speak something about my Lord." This is the qualification, enthusiasm. You may not know Kṛṣṇa very perfectly. It is not possible to know Kṛṣṇa very perfectly. Kṛṣṇa is unlimited. We cannot know Kṛṣṇa cent percent. That is not possible. But Kṛṣṇa reveals as far as possible you can understand. So if we are sincere servant of Kṛṣṇa, utsāhān, and if we serve patiently, then Kṛṣṇa reveals.

This hearing process is very, very important. But people are not interested in hearing. They are simply busy in some other duties. My Guru Mahārāja used to say... One who was not interested in hearing, he used to call him a daṇḍavat-class. Daṇḍavat-class of men. That means simply he knows how to make daṇḍavats, that's all. (laughter) Anyone who will come to him, he would see whether he is a daṇḍavat-class of man or hearing class of man. So daṇḍavat is nice, but by offering daṇḍavat, if one does not develop the intent of hearing, śravaṇam, then he is not making very much progress. As you know, because I was little interested in hearing, my Guru Mahārāja, he accepted me as his disciple. He marked this. "This boy is interested in hearing. He does not go away." Actually, I do not know. I could not understand what he was speaking in the beginning, but still I was very much interested to hear him, out of curiosity or something like that.
