Panchajanya

Panchajanya (Sanskrit: पाञ्चजन्य, IAST: Pāñcajanya) is the shankha (conch) of the Hindu preserver deity Vishnu, one of his four primary attributes.

In the Bhagavad Gita, the Panchajanya is mentioned:[6] Then, Lord Krishna blew His conchshell, called Pancajanya; Arjuna blew his, the Devadatta; and Bhima, the voracious eater and performer of extremely difficult tasks, blew his terrific conchshell called Paundram As per the Harivamsha, Krishna, the avatar of Vishnu, is described as possessing a conch shell called Panchajanya, one of his four attributes together with the mace Kaumodaki, the disc-like weapon Sudarshana Chakra, and a lotus.

Then emerged Pāñcajanya, the conch, the supreme deity of all musical instruments.In another legend, Sandipani, the guru of Krishna, Balarama, Sudama, and Uddhava, states that his son was swallowed by a whale at Prabhasa while he was on a pilgrimage, and seeks his return as his dakshina (honorarium).

The Ocean itself is stated to have informed Krishna of the existence of a great daitya of the name Panchajana dwelling in its depths, who indeed had swallowed the boy.

That region (of hell) became a void, due to the contact with Nārāyaṇa.Krishna and Balarama then returned the son back to his father, who rejoiced in surprise and hailed their names.
