Although the young brāhmaṇa described himself as having no claims to aristocracy and being an uneducated common man, still he had one good qualification: he believed that the Supreme Personality of Godhead was the topmost authority, he accepted the words of Lord Kṛṣṇa without hesitation, and he had firm faith in the Lord’s consistency. According to Prahlāda Mahārāja, another authority on the Supreme Personality of Godhead, such a staunch and faithful devotee of the Lord must be understood to be a most learned scholar: tan manye ‘dhītam uttamam (Śrīmad-Bhāgavatam 7.5.24). A pure devotee who has firm faith in the words of the Supreme Personality of Godhead is to be considered a most learned scholar, the topmost aristocrat and the richest man in the whole world. All godly qualities automatically exist in such a devotee. In the preaching work of the Kṛṣṇa consciousness movement, we, as the servant of the servant of the servant of the servant of the Supreme Personality of Godhead, fully believe in the words of Kṛṣṇa and His servants, the disciplic succession. In this way we are presenting the words of Kṛṣṇa throughout the world. Even though we are neither a rich man nor a very learned scholar, and even though we do not belong to any aristocracy, this movement is still being welcomed and is very easily spreading all over the world. Although we are very poor and have no professional source of income, Kṛṣṇa supplies money whenever we need it. Whenever we need some men, Kṛṣṇa supplies them. Thus it is stated in the Bhagavad-gītā (6.22): yaṁ labdhvā cāparaṁ lābhaṁ manyate nādhikaṁ tataḥ. Actually, if we can attain the favor of the Supreme Personality of Godhead, Kṛṣṇa, we do not need anything else. We certainly do not need those things which a mundane person considers to be material assets.
