Inside the main Amarnath cave lies an ice stalagmite resembling the Shiva Linga, which waxes during May to August and gradually wanes thereafter. This lingam is said to grow and shrink with the phases of the moon, reaching its height during the summer festival. According to Hindu mythology, this is the cave where Shiva explained the secret of life and eternity to his divine consort Parvati. Two other ice formations represent Parvati and Shiva's son, Ganesha.
