The most Handsome form Lord Shiva – Chandrashekhar

In the Devi Bhagavata Purana, the story of Lord Shiva restoring Kamadeva (the god of love) to a physical body is described. When Kamadeva attempted to disrupt Shiva's meditation he was reduced to ashes by Shiva's third eye. This event is significant because Kamadeva's actions, though bold, were intended to ensure the union of Shiva and Parvati for the greater cosmic purpose of defeating the demon Tarakasura.
Later, at the behest of Parvati and the gods, Lord Shiva, moved by compassion and understanding the necessity of Kamadeva's role in the universe, grants him a physical form.
