18 classical Smritis form the secondary canon (smriti = "that which is remembered") of Sanatana Dharma. They codify dharma — varnashrama-dharma, marriage, inheritance, criminal law, ritual prescription, daily routine, prayaschitta (expiations). Modern Hindu personal law (the Hindu Code Bills 1955-56) derives from Yajnavalkya Smriti as interpreted by the Mitakshara + Dayabhaga commentaries.

Manu Smriti · मनु स्मृति
Author: Manu (the progenitor of mankind in this Manvantara — Vaivasvata Manu)
Period: ~200 BCE - 200 CE
Size: 12 adhyayas, 2,684 shlokas
Topics — Sources of dharma, the 4 varnas, the 4 ashramas, marriage (8 types), the 16 samskaras, dietary law, women's duties, kingly duties (rajadharma), 18 forms of judicial dispute, taxation, criminal punishment, civil law (debt, inheritance, property), prayaschitta (expiation), transmigration.
Distinctive — The most-cited, most-commented-on smriti. Also the most controversial in the modern context for its varna-dharma codification. Yet structurally the model of all subsequent smritis.
Modern relevance — British colonial law treated Manu Smriti as "Hindu law" — the source-text for Anglo-Hindu jurisprudence 1772-1947. Largely superseded by the Hindu Code Bills (1955-56) but still studied in classical law schools.

Yajnavalkya Smriti · याज्ञवल्क्य स्मृति
Author: Yajnavalkya (rishi of the Shukla Yajur Veda, husband of Maitreyi)
Period: ~100 BCE - 300 CE
Size: 3 kandas — Achara (right conduct), Vyavahara (judicial), Prayaschitta (expiation). ~1,003 shlokas.
Topics — Achara: daily duties, marriage, samskaras, women, ashramas. Vyavahara: judicial procedure, witnesses, evidence, 18 disputes, property, inheritance. Prayaschitta: expiations for sins, doshas, ritual lapses.
Distinctive — Considered the most balanced and "judicial" of the smritis. More respect for women than Manu (women's property rights to "stridhana" are codified here).
Modern relevance — The Mitakshara commentary (Vijnaneshwara, 12th C) on Yajnavalkya Smriti is the FOUNDATIONAL text of Hindu inheritance law. Most of South India + North India (except Bengal) follows Mitakshara. Bengal follows the Dayabhaga commentary.
№ 3
Parashara Smriti · पराशर स्मृति
Author: Parashara (father of Veda Vyasa)
Period: ~Kali Yuga (per its own statement — meant for current age)
Size: 12 chapters, ~600 shlokas
Topics — Conduct specifically tailored for Kali Yuga — less stringent than Manu or Yajnavalkya. Widow remarriage, inter-caste marriage rules, expiations adapted for Kali.
Distinctive — Self-described as the smriti FOR Kali Yuga ("Kalau Parasharah smritih"). The other smritis are for Treta + Dvapara; this one accommodates human weakness in Kali.
Modern relevance — Often cited by reformers (Vidyasagar in his widow-remarriage campaign cited Parashara). Most relevant for current householders seeking dharma-guidance.
Topics — Dharma framed entirely as Vishnu-worship. Each rule justified as pleasing Vishnu rather than abstract dharma. Pilgrimage prescriptions, naivedyam offerings, vrata-vidhis.
Distinctive — Most Vaishnava of the smritis. Used as the authority for Vaishnava daily ritual.
Modern relevance — Foundational for Sri Vaishnava + Madhva traditions' daily conduct. Less cited in courts.
Topics — Mainly achara — daily routine, samskaras, eating rules, sleep, study, worship. Less judicial.
Distinctive — Strict on daily conduct. Famous shloka: "Snanam danam japo homo brahmacharyam vrata tapah / kshama satyamahimsa cha danadharmah samah" — listing 10 components of dharma.
Modern relevance — Cited in commentary on daily achara. Less in legal context.
№ 6
Apastamba Dharma Sutra · आपस्तम्ब धर्मसूत्र
Author: Apastamba (Krishna Yajur Veda lineage)
Period: ~600-300 BCE (one of the oldest)
Size: 2 parts, ~1500 sutras
Topics — Daily routine, samskaras, brahmacharya duties, householder duties, dharma definitions, prayaschitta.
Distinctive — Most South Indian brahmana families follow the Apastamba sutra (Apastamba-shakha). The grihya-sutra portion governs all home-rituals from upanayana to antyeshti.
Modern relevance — Daily home-rituals (samskaras, sandhya vandana, shraddha) of South Indian Smarta brahmanas follow Apastamba.
№ 7
Bodhayana Dharma Sutra · बोधायन धर्मसूत्र
Author: Bodhayana (Taittiriya / Krishna Yajur Veda lineage)
Period: ~600-300 BCE
Size: 4 parts, ~1100 sutras
Topics — Same scope as Apastamba but more pancharatra-influenced. Special focus on Vaishnava observances.
Distinctive — Bodhayana-sutra brahmanas follow this. Pancharatra Agama traditions reference Bodhayana for daily ritual structure.
Modern relevance — Sri Vaishnava brahmanas use Bodhayana sutra for daily home-rituals.
Topics — Brahmana duties, sources of dharma, 8 types of marriage, women's duties, prayaschitta, ascetic duties.
Distinctive — Earliest extant text to define "shruti and smriti and conduct of the good" as the three sources of dharma.
Modern relevance — Cited in classical legal commentaries; less in modern legal practice.
№ 9
Gautama Dharma Sutra · गौतम धर्मसूत्र
Author: Gautama (Saptarshi, founder of Nyaya)
Period: ~600-300 BCE (likely oldest extant dharma-sutra)
Size: 28 adhyayas, ~900 sutras
Topics — Brahmana code, the 4 ashramas, the 40 samskaras (Gautama lists 40 rather than 16), inheritance, criminal law, daily routine.
Distinctive — Lists the 40 samskaras (most other texts list 16-25). Apocalyptically strict on caste duties.
Modern relevance — Cited in academic studies of early dharma codification. The 40-samskara list is sometimes referenced in scholarly ritual reconstructions.
Topics — Primarily judicial — court procedure, 18 dispute categories, contracts, debt, witness examination, ordeals, criminal law. Almost no achara.
Distinctive — The first "purely legal" smriti — no ritual content, only law. Sometimes called "the Hindu Roman law".
Modern relevance — Studied by historians of jurisprudence. Cited in some judgments on traditional contract law.
Topics — Vyavahara (judicial). Considered the most authoritative on civil law alongside Yajnavalkya.
Distinctive — Brihaspati explicitly states that custom (achara) trumps even smriti — a remarkable concession to local variation. Lost-text status.
Modern relevance — Survives only through quotations in dharma-shastra digests (Mitakshara, Vyavahara Mayukha, etc).
Topics — Vyavahara, with detailed civil law sections. Famous for the doctrine of stridhana (women's separate property).
Distinctive — The MOST liberal of the smritis on women's property. Defined stridhana broadly to include all gifts to women and protected this property from husband's creditors.
Modern relevance — The stridhana doctrine continues to be invoked in Indian family courts.
Topics — Mostly achara + samskaras + prayaschitta. Less judicial.
Distinctive — Compiles teachings of other smritis with Vyasa's harmonising commentary.
Modern relevance — Cited in pancharatra + smarta tradition commentaries.
Topics — Mostly prayaschitta — expiations for ritual lapses and accidental sins (touching a corpse, breaking fast, etc).
Distinctive — Most detailed prayaschitta catalogue.
Modern relevance — Still consulted by orthodox pandits for kshudra-papa-prayaschitta.
Topics — Antyeshti rituals, sapindikarana, pitri-shraddha, garuda purana extracts.
Distinctive — Most detailed antyeshti smriti — supplements the Garuda Purana Preta-kanda.
Modern relevance — Used by purohitas conducting 13-day shraddha. The /wisdom/antyeshti procedure references Yama Smriti.
Topics — Mainly grihastha-dharma (householder duties). Family ethics, husband-wife relations, child-rearing.
Distinctive — Householder-centric. Strong on family-harmony as the foundation of dharma.
Modern relevance — Still cited for household-dispute resolution by orthodox panchayats.
Topics — Mostly daily achara + ashrama-dharma + occasional vyavahara. The famous Shankha-Likhita debate-stories are embedded in this smriti.
Distinctive — Composed by two brother-rishis who lived in perfect harmony — emblematic of dharma between equals.
Modern relevance — Less cited in modern courts but referenced in classical achara digests.
Topics — Ashrama-dharma, samskaras, daily routine, varna-dharma.
Distinctive — Closes the canonical 18. Most concise.
Modern relevance — Studied in classical Veda-shala curriculum.
The Kalpa-sutras are auxiliary to the Veda (Vedanga). They detail HOW to perform Vedic rituals. Each major Vedic shakha has its own Kalpa, consisting of: Shrauta-sutra (public yajnas), Grihya-sutra (home rituals), Dharma-sutra (rules of conduct).
