Suprabhātam is a Sanskrit word for an auspicious dawn. In Hinduism, it is a collection of hymns or verses recited in the early morning to awaken God.
Usually, they are sung early in the morning just as the sun rises. In India, I would wake up early before the sung rose to listen to a group of ladies sing the Suprabhatam in the temple at dawn. As it is sung, God within us is awoken within ourselves.
There is suprabhatam for many different forms of Hindu gods. The most well-known work of the Suprabhātam is the Veṅkaṭeśasuprabhātam recited in Tirupati awakening Veṅkaṭeśa (a form of god Vishnu). A version of the poem by the renown carnatic vocalist M. S. Subbulakshmi is extremely popular that is played every day in many houses and temples of South India.
