Adhyāya 240: Indriya–Manas–Buddhi–Ātman — The Inner Hierarchy and Restraint (इन्द्रिय-मनस्-बुद्धि-आत्म-क्रमः)
वैद्युतो अग्निरिवाकाशे दृश्यते55त्मा तथा55त्मनि । वह योगी अपने अन्तःकरणमें धूमरहित प्रज्वलित अग्नि, दीप्तिमान् सूर्य तथा आकाशमें चमकती हुई बिजलीकी ज्योतिके समान प्रकाशस्वरूप आत्माका दर्शन करता है

毗耶娑说：如同闪电或火焰在旷空中乍现可见，如是，自我（Ātman）亦在自我之中被观见。于瑜伽观修时，行者见内在之我为纯然光明——如无烟烈火，如灿然日轮，如长空电光——此乃由戒行与修持使心澄净坚住之征。

Educational Q&A
The Self is luminous and can be directly realized through yoga: when the mind is purified and concentrated, awareness turns inward and the yogin experiences the Ātman as self-revealing light—independent of external objects—symbolized by fire, sunlike brilliance, and lightning.
In the Śānti Parva’s instruction on peace and liberation, Vyāsa describes the contemplative experience of a yogin. The verse uses vivid natural images (fire/lightning in the sky) to convey how the inner Self becomes perceptible in deep meditation.
