The Lord said that but for these three items -- namely, eternal relation with God, exchange of dealings with Him and the attainment of love for Him -- all that is instructed in the Vedas is superfluous and that any other explanation of the Vedas is concocted.
The Lord further added that the Mayavada philosophy taught by Sripada Sankaracarya is an imaginary explanation of the Vedas, but it had to be taught by him (Sankaracarya) because he was ordered to teach it by the Personality of Godhead. In the Padma Purana it is stated that the Personality of Godhead ordered His Lordship Siva to deviate the human race from Him (the Personality of Godhead). The Personality of Godhead was to be so covered so that people would be encouraged to generate more and more population. His Lordship Siva said to Devi: "In the Kali-yuga, I shall preach the Mayavada philosophy, which is nothing but clouded Buddhism, in the garb of a brahmana."
After hearing all these speeches of the Lord Sri Caitanya Mahaprabhu, the Bhattacarya was struck with wonder and awe and regarded Him in dead silence. The Lord then encouraged him with assurance that there was no cause to wonder. "I say that devotional service unto the Personality of Godhead is the highest goal of human life." He then quoted the "atmarama" sloka from the Bhagavatam (1.7.10), thus assuring him that even the liberated souls who are absorbed in the spirit and spiritual realization also take to the devotional service of the Lord Hari because the Personality of Godhead has such transcendental qualities that He attracts the heart of the liberated soul too.
Then the Bhattacarya desired to listen to the explanation of this sloka. The Lord first of all asked Bhattacarya to explain it, and after that He would explain it. The Bhattacarya then explained the sloka in a scholarly way with special reference to logic. He explained the sloka in nine different ways chiefly based on logic because he was the most renowned scholar of logic of the time.
The Lord, after hearing the Bhattacarya, thanked him for the scholarly presentation of the sloka, and then, at the request of the Bhattacarya, the Lord explained the sloka in sixty-four different ways without touching the nine explanations given by the Bhattacarya.
Thus after hearing the explanation of the atmarama sloka from the Lord, the Bhattacarya was convinced that such a scholarly presentation is impossible for an earthly creature.* Before this, Sri Gopinatha Acarya had tried to convince him of the divinity of the Lord, but at the time he could not so accept Him. But the Bhattacarya was astounded by the Lord's exposition of the Vedanta-sutra and explanations of the atmarama sloka, and thus he began to think that he had committed a great offense at the lotus feet of the Lord by not recognizing Him to be Krsna Himself. He then surrendered unto Him, repenting for his past dealings with Him, and the Lord was kind enough to accept the Bhattacarya. Out of His causeless mercy, the Lord manifested before him first as four-handed Narayana and then again as two-handed Lord Krsna with a flute in His hand.
The Bhattacarya at once fell down at the lotus feet of the Lord and composed many suitable slokas in praise of the Lord by His grace. He composed one hundred slokas in praise of the Lord. The Lord then embraced him, and out of transcendental ecstasy the Bhattacarya lost consciousness of the physical state of life. Tears, trembling, throbbing of the heart, perspiration, emotional waves, dancing, singing, crying and all the eight symptoms of trance were manifested in the body of the Bhattacarya. Sri Gopinatha Acarya became very glad and astonished by this marvelous conversion of his brother-in-law by the grace of the Lord.
Out of the hundred celebrated slokas composed by the Bhattacarya in praise of the Lord, the following two are most important, and these two slokas explain the mission of the Lord in gist.
1. Let me surrender unto the Personality of Godhead who has appeared now as Lord Sri Caitanya Mahaprabhu. He is the ocean of all mercy and has now come down to teach us material detachment, learning and devotional service to Himself.
2. Since pure devotional service of the Lord has been lost in the oblivion of time, the Lord has appeared to renovate the principles, and therefore I offer my obeisances unto His lotus feet.
The Lord explained the word mukti to be equivalent to the word Visnu, or the Personality of Godhead. To attain mukti, or liberation from the bondage of material existence, is to attain to the service of the Lord.
