The conch of Vishnu, regarded in tradition as manifest in Shatrughna.
Accounts of this vary across texts and traditions. This entry primarily follows Puranic tradition, with other tellings (Valmiki Ramayana) noted where relevant.
Panchajanya is the divine conch that Vishnu carries. In some traditions, Shatrughna is regarded as a manifestation of it.
See also the Sudarshana Chakra. The identification of the four brothers with Vishnu, Shesha, the discus and the conch is a theological interpretation, not a statement in Valmiki.
