Prashna Upanishad 4.3
advanced
प्राणाग्नय एवैतस्मिन्पुरे जाग्रति। गार्हपत्यो ह वा एषोऽपानो व्यानोऽन्वाहार्यपचनो यद्गार्हपत्यात्प्रणीयते प्रणयनादाहवनीयः प्राणः॥
prāṇāgnaya evaitasminpure jāgrati | gārhapatyo ha vā eṣo'pāno vyāno'nvāhāryapacano yadgārhapatyātpraṇīyate praṇayanādāhavanīyaḥ prāṇaḥ ||
""The fires of Prana alone remain awake in this city (body). Apana is the Garhapatya (household) fire; Vyana is the Anvaharyapachana (southern) fire. Since Prana is taken from Garhapatya fire, due to this leading forth, it is called Ahavaniya (offering) fire.""
What This Means:
Even in sleep, the five pranas stay awake. They are compared to the three sacred fires of Vedic ritual. Apana, Vyana, and Prana are always working.
Going Deeper:
The three fires represent the continuous metabolic and vital processes that sustain life even during sleep. The body is a living temple with fires always burning.
How To Apply This:
Your breath continues even in sleep. Honor these tireless fires that maintain your life.
