The Vishnu Sahasranama is a sacred hymn listing a thousand names of Lord Vishnu, the preserver among the Hindu trinity, found in the Anushasana Parva of the Mahabharata. Each name describes an attribute or quality of the divine, as creator, sustainer, the all-pervading one, the source of all existence and the embodiment of righteousness (dharma). Traditionally recited on Ekadashi and other auspicious days, this hymn is considered one of the most powerful and complete expressions of devotion in Vaishnavism, believed to bring peace, prosperity and protection from difficulties to those who chant it with faith and understanding. Beyond religious ritual, scholars regard the Vishnu Sahasranama as a profound philosophical text, since many of its names describe not a personal form but the abstract, formless nature of the supreme reality that underlies the universe, making it as much a meditation on ultimate truth as an act of devotion.
