In Indian texts, Narada travels to distant worlds and realms (Sanskrit: "lokas"). He is depicted carrying a khartal (musical instrument) and veena with the name Mahathi and is generally regarded as one of the great masters of the ancient musical instrument. This instrument is known by the name "mahathi" which he uses to accompany his singing of hymns, prayers and mantras. In the Vaishnavism tradition of Hinduism, he is presented as a sage with devotion to Lord Vishnu. Narada is described as both wise and mischievous in some humorous tales. Vaishnav enthusiasts depict him as a pure, elevated soul who glorifies Vishnu through his devotional songs, singing the names "Hari" and "Narayana", and therein demonstrating bhakti yoga. The Narada Bhakti Sutra is attributed to him.
