The above verse is from ÅšrÄ«mad-BhÄgavatam (10.14.29). The Brahma-saá¹hitÄ states, vedeá¹£u durlabham adurlabham Ätma-bhaktau (Bs. 5.33). Although the Supreme Personality of Godhead, Kṛṣṇa, is the ultimate goal of knowledge (vedaiÅ› ca sarvair aham eva vedyaḥ), one who is not a pure devotee and who is not engaged in the service of the Lord cannot understand Him. Lord BrahmÄ therefore confirms this. Vedeá¹£u durlabham: “It is very difficult to understand the Supreme Lord simply through one’s studies.†Adurlabham Ätma-bhaktau: “However, it is very easy for the devotees to capture the Lord.†The Lord is known as ajita (unconquerable). No one can conquer the Supreme Personality of Godhead, but the Lord consents to be conquered by His devotees. That is His nature. As stated in the Padma PurÄṇa:
ataḥ Å›rÄ«-kṛṣṇa-nÄmÄdi na bhaved grahyam indriyaiḥ
sevonmukhe hi jihvÄdau svayam eva sphuraty adaḥ
Being pleased by devotional activities, the Lord reveals Himself to His devotees. That is the way to understand Him.
The verse from ÅšrÄ«mad-BhÄgavatam quoted by GopÄ«nÄtha Ä€cÄrya was originally spoken by Lord BrahmÄ when he was defeated by Lord Kṛṣṇa. Lord BrahmÄ had stolen all the calves and cowherd boys in order to test Kṛṣṇa’s power. Lord BrahmÄ admitted that his own extraordinary powers within the universe were not in the least comparable to the unlimited powers of Lord Kṛṣṇa. If Lord BrahmÄ can make a mistake in understanding Kṛṣṇa, what to speak of ordinary persons, who either misunderstand Kṛṣṇa or falsely present a so-called incarnation of Kṛṣṇa for their own sense gratification.
