In Hindu mythology, the god known for his blue skin and playful nature is Krishna. He is revered as a supreme deity and is celebrated for his roles as a divine lover, teacher, and protector. His playful and mischievous demeanor, especially in childhood, embodies the joy and liveliness of existence. Krishna's life teachings found in the Bhagavad Gita emphasize concepts of dharma (duty) and bhakti (devotion). His narratives embody spiritual wisdom, making him a central figure in Hindu belief and a symbol of divine love.
