The Manusmriti (or Manu Smriti) is an ancient Sanskrit text that is the most authoritative work on Hindu law (Dharma). It codifies social duties, laws, and ethical conduct in ancient Indian society. While it touches on society and philosophy, its primary purpose is as a legal treatise outlining duties, obligations, and jurisprudence. It is not a work on medicine, primarily about society, or purely philosophical - it is fundamentally a legal and dharmic text.
