Gajendra moksha (Sanskrit: गजेन्द्रमोक्षः) is Puranic legend from Bhagavata Purana. Lord Vishnu came down to earth to protect Gajendra(elephant) from the death clutches of Makara (Crocodile).
Gajendra was the King of elephants. One hot day, he proceeded to the lake with his family to cool off in its fresh waters. But from within the lake a crocodile appeared who attacked him and would not let go of him. When the family and relatives saw ‘death’ coming close to Gajendra, and everyone realised that everything was lost, they left Gajendra alone. Gajendra prayed to god Vishnu to save him. Vishnu came to the aid of Gajendra, who offered a lotus to the god. Vishnu attacked the crocodile and saved His Loved One.
Gajendra, in his previous life was a great devotee called Indradyumna who was also a great king. One day, Agastya, a great sage came to visit the king. Indradyumna did not receive the Sage with the respect that the latter expected. The enraged Agastya cursed the king to become an elephant in his next birth, as he sat heavy on his seat and did not rise to greet him.
The crocodile in its last life was a king called HuHu in the Gandharva planet. Once while enjoying himself in the waters, he pulled the leg of a sage. The enraged sage cursed the king to become a crocodile in his next life. The repentant HuHu asked for pardon. The Sage proclaimed that though he could not retrieve the curse, the crocodile would be liberated from the cycle of birth and death when Gajendra would be saved by the Lord God Himself.
