prāṇa

Prāṇa is the Sanskrit name for breath understood as both respiration and life-force — a single word for what physiology and metaphysics treat as separate phenomena. Etymologically connected to ātman through the breath/self semantic doubling found across several Indo-European languages, prāṇa is the linguistic move that lets later Indic traditions theorize breath as a bridge to the self rather than as a body function alone.

Within yogic and broader Indic philosophical traditions, prāṇa is not one substance but a structured field — typically articulated in five prāṇas (prāṇa, apāna, samāna, udāna, vyāna) governing different bodily and energetic functions. The term thus opens onto a substantial conceptual apparatus that translation into "breath" or "life-force" alone cannot deliver.

Notes

Cross-language analogues — Greek pneuma, Hebrew ruach, Latin spiritus, Chinese qi — are typologically suggestive but not literal equivalents. The shared semantic territory (breath / vitality / animating principle) does not warrant the inference that the underlying frameworks are the same. Each carries the metaphysical structure of the civilization that articulated it. The architecture preserves prāṇa as prāṇa and refuses the synthesizing move that would domesticate it into a generic "breath/spirit" concept the source civilizations did not articulate.
