Kalpa
Kalpa is one of the six Vedangas, dealing with ritual, ceremonies, and the procedures for Vedic rites and sacrifices.
- Kalpa is the Vedanga of ritual procedure — the practical guide to performing Vedic ceremonies correctly.
- It is called the 'hands of the Vedas' — providing the practical implementation of Vedic injunctions.
- Divided into four categories: Shrauta Sutras, Grihya Sutras, Dharma Sutras, and Shulba Sutras.
- Shrauta Sutras describe the major public sacrifices (yajnas) like the Ashvamedha and Agnishtoma.
- Grihya Sutras cover domestic rituals — birth, naming, education, marriage, and death ceremonies.
- Dharma Sutras lay out rules of conduct — the basis of later Dharmashastra tradition.
- Shulba Sutras contain precise geometric rules for constructing Vedic fire altars — some of the earliest recorded geometry.
- The Baudhayana Shulba Sutra contains what is effectively the Pythagorean theorem, centuries before Pythagoras.

Dharma Sutra — Duties of the Four Ashramas
Apastamba Dharma Sutra · Chapter 1 · Verse 1
ब्रह्मचर्यं गार्हस्थ्यं वानप्रस्थः संन्यासश्च। एते चत्वार आश्रमाः। ब्रह्मचर्यं विद्याभ्यासः, गार्हस्थ्यं गृहस्थधर्मः। वानप्रस्थः वनवासः, संन्यासः सर्वत्यागः॥
brahmacaryaṃ gārhasthyaṃ vānaprasthaḥ saṃnyāsaś ca | ete catvāra āśramāḥ | brahmacaryaṃ vidyābhyāsaḥ, gārhasthyaṃ gṛhasthadharmaḥ | vānaprasthaḥ vanavāsaḥ, saṃnyāsaḥ sarvatyāgaḥ ||
The four Āśramas (life-stages) and their duties: (1) Brahmacarya — student stage: celibacy and Vedic learning; (2) Gārhasthya — householder stage: marriage, children, social duties; (3) Vānaprastha — forest retirement: gradual withdrawal; (4) Saṃnyāsa — renunciation: complete withdrawal from worldly life. The Āpastamba and Baudhāyana Dharma Sūtras detail the specific duties of each stage.
The Four Divisions of Kalpa
Kalpa Vedanga — Introduction · Chapter 1 · Verse 1
श्रौतसूत्राणि, गृह्यसूत्राणि, धर्मसूत्राणि, शुल्बसूत्राणि च। एते चत्वारः कल्पस्य विभागाः। यज्ञविधानं कल्पः — इति लक्षणम्॥
śrautasūtrāṇi, gṛhyasūtrāṇi, dharmasūtrāṇi, śulbasūtrāṇi ca | ete catvāraḥ kalpasya vibhāgāḥ | yajñavidhānaṃ kalpaḥ — iti lakṣaṇam ||
Kalpa (ritual procedure) is divided into four categories: (1) Śrauta Sūtras — public fire rituals based on the Vedas; (2) Gṛhya Sūtras — domestic rituals and life-cycle rites; (3) Dharma Sūtras — social law and duties; (4) Śulba Sūtras — geometry for Vedic altar construction. Kalpa is the hand of the Veda — it enacts what the Veda prescribes.
Grhya Sutras — The Sixteen Life-Rites (Samskaras)
Ashvalayana Grhya Sutra / Paraskara Grhya Sutra · Chapter 1 · Verse 1
गर्भाधानं पुंसवनं सीमन्तोन्नयनम्। जातकर्म नामकरणं निष्क्रमणमन्नप्राशनम्। चूडाकर्म कर्णवेधोपनयनं च। वेदारम्भः समावर्तनं विवाहः च। वानप्रस्थः संन्यासो मृत्युसंस्कारश्च — षोडशैते॥
garbhādānaṃ puṃsavanaṃ sīmantonnayanam | jātakarma nāmakaraṇaṃ niṣkramaṇam annaprāśanam | cūḍākarma karṇavedhopanayanaṃ ca | vedārambhaḥ samāvartanaṃ vivāhaḥ ca | vānaprasthaḥ saṃnyāso mṛtyusaṃskāraś ca — ṣoḍaśaite ||
The sixteen Saṃskāras (life-purification rites) as prescribed in the Gṛhya Sūtras: (1) Garbhādhāna (conception), (2) Puṃsavana (foetal rite), (3) Sīmanta (parting of hair), (4) Jātakarma (birth), (5) Nāmakaraṇa (naming), (6) Niṣkramaṇa (first outing), (7) Annaprāśana (first solid food), (8) Cūḍākarma (head-shaving), (9) Karṇavedha (ear-piercing), (10) Upanayana (sacred thread), (11) Vedārambha (beginning Vedic study), (12) Samāvartana (graduation), (13) Vivāha (marriage), (14) Vānaprastha (forest retirement), (15) Saṃnyāsa (renunciation), (16) Antyeṣṭi (last rites).
Dharma Sutra — Four Sources of Dharma
Apastamba Dharma Sutra / Manu Smriti · Chapter 1 · Verse 1
वेदः स्मृतिः सदाचारश्च स्वस्य च प्रियमात्मनः। एतच्चतुर्विधं प्राहुः साक्षाद् धर्मस्य लक्षणम्॥
vedaḥ smṛtiḥ sadācāraś ca svasya ca priyam ātmanaḥ | etac caturvidhaṃ prāhuḥ sākṣād dharmasya lakṣaṇam ||
The four sources of Dharma: (1) Veda (scripture), (2) Smṛti (remembered law texts), (3) Sadācāra (good conduct of the virtuous/learned), (4) Priya ātmanas — what is pleasing to one's own soul (conscience). These four, in order, are the direct definition of Dharma. Based on Manu Smriti 2.12 and related Dharma Sutra passages.
