Smṛti, also spelled smriti or smruti, is a body of Hindu texts representing the remembered, written tradition in Hinduism, rooted in or inspired by the Vedas. Smṛti works are generally attributed to a named author and were transmitted through manuscripts, in contrast to Vedic or śruti literature, which is based on a fixed text with no specific author, and preserved through oral transmission. Smṛti texts are derivative, secondary works and are considered less authoritative than śruti in Hinduism, except in the Mīmāmsa school of Hindu philosophy. The authority of smṛti accepted by orthodox schools is derived from that of śruti, on which it is based.
