Achyutam Keshavam
Achyutam Keshavam is a bhajan built almost entirely out of names. Rather than telling a story or making a request, it moves through the titles of Vishnu and his avatars one after another, and the devotion lies in the naming itself.
Each name carries its own sense. Achyuta means the one who does not fall or fail, the imperishable. Keshava is read variously as the one with beautiful hair or the slayer of the demon Keshi. Rama and Krishna name the two avatars most present in household worship. Narayana points to the one who rests upon the cosmic waters, Damodara recalls the child Krishna bound at the waist with a rope, and Vasudeva names him as the son of Vasudeva.
This practice of reciting divine names is old and has its own term, nama-sankirtana, and its own theology: that the name and the named are not separate, so that to speak the name attentively is already to be in the presence.
The bhajan is sung through the year and is especially common at Janmashtami and during Vaishnava gatherings. Its simple structure makes it easy for a congregation to join without knowing the words in advance.
