Vamana Avatara -7
At Mathura, an army of hermits (Virāgi) who were armed with the name of the Lord (Nāmasaṅkīrtane), true Vaiṣṇavas were suppressing the demon of desires called Kali. The sanctity of the place is the protective wall that keeps rest of the evil forces away. Srī Vādirājaru gives a marvelous reflection that for this army, their past deeds are the armor.
