Taittiriya Upanishad 3.4
intermediate
स तपोऽतप्यत। स तपस्तप्त्वा। मनो ब्रह्मेति व्यजानात्। मनसो ह्येव खल्विमानि भूतानि जायन्ते। मनसा जातानि जीवन्ति। मनः प्रयन्त्यभिसंविशन्तीति।
sa tapo'tapyata | sa tapastaptvā | mano brahmeti vyajānāt | manaso hyeva khalvimāni bhūtāni jāyante | manasā jātāni jīvanti | manaḥ prayantyabhisaṃviśantīti |
"He performed austerity. Having performed austerity, he understood: Mind is Brahman. From mind indeed these beings are born. By mind they live once born. Into mind they enter upon departing."
What This Means:
Further meditation reveals mind as Brahman. All creation, sustenance, and dissolution happen in mind.
Going Deeper:
This corresponds to Manomaya kosha. Mind is subtler than prana, but still an object of awareness, not awareness itself.
How To Apply This:
Mind shapes your reality. But the question remains: What is aware of mind?
