ພະວາຍຸກ່າວວ່າ: «ເຂົາເວົ້າກັນວ່າ ‘ແສງທີສາມ’; ແລະນັ້ນເອີ້ນວ່າ ວິໄສທັດພາຍໃນ (ອັດຍາດມະ)—ປັນຍາທີ່ເຫັນອັດຕາ ເກີນກວ່າອາຍະຕະນະພາຍນອກ».

Educational Q&A
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.
