Brihaspati recited the mantra by having the prepared defense formula tied to the hands of Indra and all the gods.
Due to the force of that mantra, the demon Raj Bali was bound. The scriptures say that the Rakshabandhan festival is the day when the sages who came out from the mouth of Brahmaji will bind the Panchatattva, while in the 'Brahman' avatar, Vishnu made a commitment to the sacrifice of the Daityaraja and released the three people as a gift.
