As per Hindu mythology, there was a long battle occurred between the Gods and the Demons, where the Demons won after a long-lasting fight of twelve years. Post battle, the Demons seized not only the throne of Gods-Indra, but also the three worlds i.e Swarg, Martha and Patal. God Indra went to God Brihaspati for his advice. Brihaspati advised Indra to chant some mantras for his protection. Dev Guru Brihaspati started the process of prayer by chanting the mantras in the month of Shravan on a Full Moon day. During this prayer period a sacred thread tied to a packet comprising the blessings, which has been tied to God Indra’s wrist by his wife ‘Indrani’ after the ceremony. Because of these blessings, Lord Indra got his power to conquer the Demons and recover his missing kingdom.
