Sri Caitanya Mahaprabhu accepted sannyasa from the Bharati sampradaya (community), which belongs to the disciplic succession of Sankaracarya. Sankaracarya introduced names for his sannyasa disciples, and these are ten in number. Out of these, the surnames Tirtha, Asrama and Sarasvati are considered topmost. In the monastery at Srngeri, the surname Sarasvati is considered first class, Bharati second class and Puri third class. A sannyasi who has very nicely understood the slogan tat tvam asi and who takes his bath at the confluence of the rivers Ganges, Yamuna and Sarasvati is called a Tirtha. A person who is very eager to accept sannyasa, who is detached from worldly activities, who has no desire for any kind of material facilities, and who is thus saved from repeated birth and death is known as Asrama. When a sannyasi lives in a beautiful, solitary place in the forest and is freed from all material desires, he is called Vana. A sannyasi who always lives in the forest and renounces all connection with the world in order to be elevated to the heavenly planets, where he can live in the Nandana-kanana, is called Aranya. One who prefers living in the mountains engaging in the study of the Bhagavad-gita and whose intelligence is fixed is called Giri. One who prefers living in great mountains, even among ferocious animals, to attain the summit of philosophical speculation (understanding that the essence of this material world is useless) is called Parvata. A sannyasi who has dipped into the ocean of the Absolute Truth and collected some valuable stones of knowledge from that ocean, who never falls from the regulative principles of a sannyasi, is called Sagara. One who has learned the classical art of music, who engages in its culture, and who has become expert and completely aloof from material attachment is called Sarasvati. Sarasvati is the goddess of music and learning, and in one hand she holds a musical instrument called a vina. A sannyasi who is always engaged in music for spiritual elevation is called Sarasvati. One who has become completely educated and is freed from all kinds of ignorance and who is never unhappy, even in a distressed condition, is called Bharati. One who has become very expert in absolute knowledge, who is situated in the Absolute Truth, and who always discusses the Absolute Truth is called Puri.
