Sri Caitanya Mahaprabhu wanted to point out to the Tattvavadi acarya, who belonged to the Madhvacarya-sampradaya, that the general behavior of the Tattvavadis did not favor pure devotional service, which must be devoid of the taints of fruitive activity and speculative knowledge. As far as fruitive activity is concerned, the contamination is the desire for elevation to a higher standard of life, and for speculative knowledge the contamination is the desire to merge into the existence of the Absolute Truth. The Tattvavada-sampradaya of the Madhvacarya school sticks to the principle of varnasrama-dharma, which involves fruitive activity. Their ultimate goal (mukti) is simply a form of material desire. A pure devotee should be free from all kinds of material desire. He simply engages in the service of the Lord. Nonetheless, Caitanya Mahaprabhu was pleased that the Madhvacarya-sampradaya, or the Tattvavada-sampradaya, accepted the transcendental form of the Lord. This is the great qualification of the Vaisnava sampradayas.
