Adi Shankaracharya's 8th century poetic hymn "Bhaja Govindam" is both a devotional song praising God and a philosophical treatise containing the essence of Indian philosophy. In just a few concise verses, it urges the reader to meditate on God and understand the true nature of reality, warns against attachment to worldly things like wealth and youth that are impermanent, and advises cultivating detachment and knowledge of the self to achieve liberation from rebirth.
