The Laws of Manu, in Sanskrit the Manava Dharmasastra, is a classical Hindu treatise on dharma: the sacred law, duty, and right conduct. Georg Buehler's 1886 translation presents it in twelve lectures or chapters. It is a historical religious and legal document of early India, and it reads as one, mixing cosmology, ritual rule, social regulation, and moral teaching in a single frame. The work is framed as Manu's reply when the great sages approach him and ask him to declare the law.
It begins with creation. A self-existent power brings forth the world, is born within a golden egg as Brahman, and shapes ordered beings from the formless. Within this account the four castes appear, said to spring from the mouth, arms, thighs, and feet of the primal being. From the start, then, the social order is presented as part of the order of the cosmos, and the duties that follow are described as built into how the world was made.
Much of the treatise assigns duties. To the Brahmana it gives teaching, study, sacrifice, and the giving and receiving of alms; to the Kshatriya, protection of the people and the bearing of arms; to the Vaisya, trade, cattle, and cultivation; and to the Sudra, service of the other three. Alongside caste runs the scheme of the four orders of life, the student, the householder, the hermit, and the ascetic, all of which the text says rest upon the householder, since the householder supports the rest as air supports living creatures.
The later lectures turn to the king, to civil and criminal law, and to the settling of disputes. Here the central instrument is danda, punishment. The text declares that punishment alone governs and protects all beings, and that the wise treat it as identical with the law itself. The king is charged with wielding it justly, and a long body of rules covers marriage, inheritance, property, debt, witnesses, penance, and the purification owed after various faults.
The final lecture draws the system together through karma and rebirth. Action of mind, speech, and body yields good or evil fruit and fixes a person's future station among the high, the middling, and the low. Each being is born alone and dies alone, and reaps its own merit and sin alone. Justice, the text says, is the one companion that follows a person past death. So the treatise closes by binding ritual, social duty, law, and conduct to the moral weight that deeds carry across a long chain of births.
