raja kahe,-bhatta tumi vijna-siromani
tumi tanre 'krsna' kaha, tate satya mani
raja kahe—the King said; bhatta—Sarvabhauma Bhattacarya; tumi—you; vijna-siromani—the most experienced learned scholar; tumi—you; tanre—Him; krsna kaha—address as Lord Krsna; tate—your statement; satya mani—I accept as true.
The King said, "Bhattacarya, you are the most learned and experienced person I know. Therefore when you address Sri Caitanya Mahaprabhu as Lord Krsna, I accept this as the truth.
This is the way to advance in spiritual science. One must accept the words of an acarya, a bona fide spiritual master, to clear the path for spiritual advancement. This is the secret of success. However, one's guide must be a spiritual master who is actually an unalloyed devotee strictly following the instructions of the previous acarya without deviation. Whatever the spiritual master says must be accepted by the disciple. Only then is success certain. This is the Vedic system.
Sarvabhauma Bhattacarya was a brahmana and a realized soul, whereas Prataparudra was a ksatriya. Ksatriya kings used to obey very faithfully the orders of learned brahmanas and saintly persons, and in this way they would rule their country. Similarly, vaisyas used to follow the king's orders, and sudras used to serve the three higher castes. In this way the brahmanas, ksatriyas, vaisyas and sudras used to live cooperatively, performing their respective duties. Consequently society was peaceful, and people were able to discharge the duties of Krsna consciousness. Thus they were happy in this life and able to return home, back to Godhead.
