Definition
Hindu cosmology is the set of traditional Indian beliefs and philosophical concepts concerning the origin, structure, evolution, and ultimate fate of the universe as presented in Hindu scriptures, commentaries, and associated mythological literature.
Overview
Hindu cosmological models describe the universe as an infinite, cyclical system composed of multiple realms, dimensions, and temporal cycles. Central to these models are the notions of kalā (time), yugas (ages), kalpas (eons), and the recurring processes of creation (sṛṣṭi), preservation (sthiti), and dissolution (pralaya). The cosmos is often depicted as a multi‑layered structure consisting of:
- Bhu‑loka – the earthly realm where humans reside.
- Svarga – heavenly realms of the devas (gods).
- Pātāla – subterranean realms inhabited by various beings.
- Higher spiritual planes such as Brahmaloka, Vaikuntha, and Kailasa, regarded as abodes of supreme deities.
Time is measured in vast units: a mahayuga (four yugas) lasts 4.32 million years; 1,000 mahayugas constitute a kalpa (a "day of Brahma"); a full cycle of Brahma’s lifespan spans 311.04 billion years. After each kalpa, the universe undergoes a period of dissolution (pralaya) before re‑creation.
Key texts that elaborate these ideas include the Rig‑veda (e.g., Nasadiya Sukta), the Puranas (especially the Vishnu and Brahma Puranas), the Mahabharata, and philosophical treatises such as the Sāṁkhya and Vedānta schools. While mythic narratives present vivid cosmological imagery, philosophical commentaries interpret them allegorically or metaphysically.
Etymology/Origin
The term combines “Hindu,” derived from the Persian word Hind referring to the region around the Indus River, with “cosmology,” from the Greek kosmos (order, universe) and ‑logia (study of). Within Sanskrit literature, concepts related to cosmology are expressed by words such as brahmand (the "world egg" or "universal womb") and lokadhātu (the “realm of worlds”).
Characteristics
| Aspect | Description |
|---|---|
| Cyclicity | The universe undergoes endless cycles of creation, preservation, and dissolution, without a singular beginning or ultimate end. |
| Multiple Universes | Some Puranic passages describe countless lokas (worlds) and Brahmandas (cosmic eggs) existing simultaneously, implying a multiverse-like notion. |
| Temporal Magnitude | Time scales vastly exceed human perception, ranging from yugas (thousands of years) to kalpas (billions of years). |
| Divine Agency | Creation is attributed to deities such as Brahma (the creator), Vishnu (the preserver), and Shiva (the destroyer), each embodying a functional aspect of cosmic order. |
| Philosophical Interpretation | Schools like Advaita Vedanta view cosmological narratives as symbolic representations of underlying non‑dual reality (Brahman), whereas Sāṁkhya treats them as enumerations of material (prakṛti) and conscious (purusha) principles. |
| Integration with Ethics | The cosmological framework underpins concepts of dharma (righteousness) and karma (action), linking individual conduct to cosmic order. |
