Shruti — The Revealed Knowledge

Shruti literally means "that which is heard." These are considered apaurusheya (not of human origin) — revealed to seers (rishis) in deep meditation.

The Four Vedas:

Four-fold Structure within each Veda:

1. Samhita — Mantras (hymns)
2. Brahmana — Explanations of rituals
3. Aranyaka — Forest treatises (transitional, meditative)
4. Upanishad — Philosophical conclusions (also called Vedanta, "end of Veda")

Smriti — The Remembered Texts

Smriti are works composed by human authors based on insights from Shruti.

The Six Vedangas — Auxiliary Disciplines

To preserve and understand the Vedas, six "limbs" (Vedangas) were developed:

The Upavedas — Applied Sciences

Each Veda has a corresponding Upaveda (sub-Veda):

• Ayurveda (from Atharva) — Medicine
• Dhanurveda (from Yajur) — Military science
• Gandharvaveda (from Sama) — Music & performing arts
• Sthapatyaveda / Arthashastra (from Rig) — Architecture & polity

Key Terms — Lesson 1.2 (Shruti, Smriti & Vedangas)

The Shruti–Smriti split and the names of the six Vedangas are perennial one-mark and matching questions.

Shruti — "That which is heard"; revealed, apaurusheya texts — the 4 Vedas with their Samhitas, Brahmanas, Aranyakas and Upanishads. Smriti — "That which is remembered"; texts composed by human authors (Itihasa, Puranas, Dharmashastras, Sutras). Apaurusheya — "Not of human origin"; the quality attributed to Shruti, revealed to rishis in meditation. Samhita — The mantra/hymn portion of a Veda. Brahmana — Prose explanations of the rituals. Aranyaka — "Forest treatises"; the transitional, meditative layer. Upanishad (Vedanta) — The philosophical conclusion, literally the "end of the Veda". Itihasa — Epic history (Ramayana, Mahabharata) — dharma shown in action. Vedanga — The six "limbs" that preserve and decode the Veda: Shiksha, Kalpa, Vyakarana, Nirukta, Chhandas, Jyotisha. Upaveda — Applied science attached to each Veda (Ayurveda, Dhanurveda, Gandharvaveda, Sthapatyaveda).

Self-check

1. Which category is "remembered", not "revealed"? (Smriti)
2. Name the four-fold structure inside each Veda. (Samhita, Brahmana, Aranyaka, Upanishad)
3. Which Vedanga deals with grammar, and whose work defines it? (Vyakarana — Panini's Ashtadhyayi)
4. Which Upaveda is attached to the Atharva Veda? (Ayurveda)
5. Why is the Upanishad called Vedanta? (It is the philosophical "end of the Veda")
