Adhyāya 42 — Mahābhūta–Indriya–Adhyātma-Vyavasthā
Brahmā’s Instruction on Elements and Faculties
तृतीयं ज्योतिरित्याहुश्नक्षुरध्यात्ममुच्यते
tṛtīyaṃ jyotir ity āhuḥ nakṣur adhyātmam ucyate
ព្រះវាយុមានព្រះបន្ទូលថា៖ «គេហៅថា ‘ពន្លឺទីបី’; ហើយវាត្រូវបានហៅថា ចក្ខុវិស័យខាងក្នុង (អធ្យាត្ម)—ការយល់ឃើញដែលអាចមើលឃើញអាត្មា លើសពីអារម្មណ៍ខាងក្រៅ»។
वायुदेव उवाच
The verse points to a higher kind of illumination beyond ordinary sensory light: an inward, spiritual ‘light’ identified with adhyātma—self-knowledge or inner realization—through which one discerns the Self and right understanding.
Vāyudeva is speaking in a didactic context, defining a doctrinal term: he explains that what some call the ‘third light’ is actually the inner spiritual faculty (adhyātma), shifting attention from external perception to inward realization.
