Commenting on the word parama-vaisnava, Srila Bhaktivinoda Thakura says that anyone who desires to merge into the existence of the Lord cannot be a pure Vaisnava, but because Ramadasa Visvasa was a great devotee of Lord Ramacandra, he was almost a Vaisnava. In those days, no one could distinguish between a pure Vaisnava and a pseudo Vaisnava. Therefore Ramadasa Visvasa was known as a Vaisnava because he worshiped Lord Ramacandra.
