"[6] The Jai Bajrangbali Temple on Netrani Island, Karnataka, is known for its annual ritual of offering mangoes to Lord Hanuman during a specific festival.

This tradition is linked to a tale from the Valmiki Ramayana (Kishkindha Kanda, Sarga 67), where the young Hanuman mistook the Sun for a ripe mango and leapt toward it, causing cosmic disturbances.

The tranquil setting of Netrani Island enhances the temple’s spiritual appeal, drawing worshippers to honor Hanuman’s boundless energy and devotion.
