Bhagavad Gita 13.17
ज्योतिषामपि तज्ज्योतिस्तमसः परमुच्यते।ज्ञानं ज्ञेयं ज्ञानगम्यं हृदि सर्वस्य विष्ठितम्॥
jyotiṣāmapi tajjyotistamasaḥ paramucyate |jñānaṃ jñeyaṃ jñānagamyaṃ hṛdi sarvasya viṣṭhitam ||
That Light of all lights is said to be beyond darkness: knowledge, the knowable, and the goal of knowledge, seated in the hearts of all.
It is the light of lights, beyond the reach of darkness; the wisdom, the only thing worth knowing or that wisdom can teach; the presence in the hearts of all.
Our plain-language meaning of this verse is waiting for scholar review.
