The four sources of Dharma
Manusmṛti 2.12 lists the four sources from which Dharma is known: Śruti (the Vedas — the primary source); Smṛti (the remembered tradition — the Dharmaśāstra texts); Sadācāra (the conduct of good people — the practice of the learned in one's own region); and Ātmatuṣṭi (what is pleasing to oneself — the conscience). The hierarchy matters: where Smṛti conflicts with Śruti, Śruti prevails; where regional practice conflicts with Smṛti, the scholar must determine which is authoritative. This pluralism within the system is one of its most distinctive features. Source: Olivelle (2005), MS 2.12.
Rājadharma — the king's Dharma
A substantial portion of the major Smṛtis is devoted to Rājadharma (the king's Dharma) — the duties and prerogatives of the ruler. The Manusmṛti's account (7.1–226): the king is constituted from particles of eight divine guardians of the directions; he must appoint ministers and priests; maintain a treasury, army, and intelligence service; administer justice; protect the Varṇa system and the Āśrama system; and conduct himself according to the Arthaśāstra's practical prescriptions. The relationship between Dharmaśāstra (ideal law) and Arthaśāstra (practical statecraft) is one of the most productive tensions in Indian political philosophy.

P.V. Kāṇe's History of Dharmaśāstra — the scholarly monument
Pāṇḍuraṅga Vāmana Kāṇe (1880–1972) spent four decades compiling the most comprehensive treatment of Dharmaśāstra in any language: the five-volume History of Dharmaśāstra (Bhandarkar Oriental Research Institute, Pune, 1930–1962), covering approximately 6,500 pages. The work surveys every major Dharmaśāstra text — its authorship, dating, relationship to other texts, and content — in exhaustive detail. It remains the indispensable reference for scholars of Sanskrit law. Kāṇe received the Bharat Ratna (India's highest civilian honour) in 1963 for this achievement. Source: Olivelle (2005).
Dharmaśāstra and modern Indian law
The relationship between Dharmaśāstra and modern Indian law is direct and contested. The British colonial administration (through the work of scholars like William Jones and Henry Thomas Colebrooke) translated and partially codified selected Dharmaśāstra texts as "Hindu Law" — a process that froze living, contested traditions into fixed legal codes and created a unified "Hindu personal law" that had never existed in that form. Post-independence Indian legislation — the Hindu Marriage Act 1955, the Hindu Succession Act 1956, the Hindu Adoption and Maintenance Act 1956 — codified Hindu personal law in secular statutory form, largely replacing the earlier Dharmaśāstra-based system. The tension between the codified Dharmaśāstra tradition and the secular Indian legal system continues to generate political controversy (debates over a Uniform Civil Code).
