Prana (breath — base time-unit)

prāṇa
tmp-prana

Definition

In the BS time-reckoning (II), Prana is the duration of one breath (one inspiration + one expiration), the base human-scaled unit from which the larger time-measures are built (6 pranas = 1 vinadi/vighati; thence nadika, muhurta, day...).

Prāṇa relevance

⚑ The standout prana-axis node of the Jyotisha core: the jyotisha time-system is literally anchored on the HUMAN BREATH — cosmic and ritual time is counted in pranas (breaths). So human respiration is the yardstick of astronomical time [CLASSICAL — BS II]. The stronger claim that this breath-time IS the vital-prana of the body (i.e. that cosmic time and bodily prana are one principle) is NOT made by BS — that identification would be SPECULATIVE and is flagged, not asserted. But the breath-as- measure-of-time fact is a clean, citable bridge between body and cosmos on the time axis, complementing the body↔building (ch.53) and body↔earth (ch.54) homologies on the space axis.

  • ↔Time as the Divine Breath (the science of time; breath↔time↔Sun)Modern
    Frawley's 'science of time' (grounded in Maitri Upanishad VI.1) makes the human BREATH (Prana) the inner counterpart of cosmic/solar time: 'by the movement of the outer Self [Sun] the movement of the inner Self [Prana/breath] is measured.' This ECHOES the Brihat Samhita's tmp-prana, where prana = the duration of one breath = the base human-scaled unit of the entire jyotisha time-system (cosmic time literally counted in human breaths). The file deliberately CROSS-REFERENCES rather than merges: Frawley's Upanishad-grounded version asserts a reciprocal breath<->Sun (inner<->outer Self) IDENTITY, which is doctrinally STRONGER than tmp-prana's bare time-UNIT use (Book-1 Q38 records that BS does not assert the time-prana IS the vital/bodily prana). This edge records the resonance, NOT a resolution.
