Vāyu

Vāyu

Vāyu — wind or air — is the second of the five mahābhūtas (great elements) in the traditional Indian cosmological order. It arises from ākāśa (space) in the sequential evolution of cosmic elements. Its tanmātra (elemental sensory quality) is sparśa (touch) — the sense of touch or tactile sensation. The connection between Vāyu and touch reflects the experience of wind as something perceived through the skin — the breath of air against the body. In the physical cosmos, Vāyu is the medium of all movement, the carrier of breath, the force that drives ocean currents and atmospheric phenomena.

In the microcosm of the human body, Vāyu manifests as the five prāṇas — the five vital breath-forces that sustain physical life: prāṇa (outgoing breath, residing in the chest, governs respiration and intake), apāna (downward breath, governs elimination and downward movements), vyāna (diffuse breath, pervading the entire body, governs circulation), udāna (upward breath, in the throat, governs speech, the upward life-force, and the departure of the soul at death), and samāna (equalizing breath, in the navel region, governs digestion and the fire of transformation). These five prāṇas are considered the cosmic Vāyu individualized within each living being.

In the Antaryāmī Brāhmaṇa of the Bṛhadāraṇyaka Upaniṣad (3.7), Yājñavalkya declares to Uddālaka: 'yaḥ prāṇe tiṣṭhan prāṇād antaraḥ, yaṃ prāṇo na veda, yasya prāṇaḥ śarīram, yaḥ prāṇam antaro yamayati' — 'He who stands within Vāyu/prāṇa, whom Vāyu/prāṇa does not know, whose body is Vāyu/prāṇa, who controls Vāyu/prāṇa from within — He is your ātman, the inner controller, the immortal.' Rāmānuja uses this Antaryāmī Brāhmaṇa as a key scriptural proof-text for his doctrine that Bhagavān is the antaryāmin (inner controller) of all elements and all souls, that the entire cosmos is His body.
