ज्योतिषामपि तज्ज्योतिस्तमस: परमुच्यते |
ज्ञानं ज्ञेयं ज्ञानगम्यं हृदि सर्वस्य विष्ठितम् || 18||
jyotiṣhām api taj jyotis tamasaḥ param uchyate
jñānaṁ jñeyaṁ jñāna-gamyaṁ hṛidi sarvasya viṣhṭhitam
BG 13.18: He is the source of light in all luminaries, and is entirely beyond the darkness of ignorance. He is knowledge, the object of knowledge, and the goal of knowledge. He dwells within the hearts of all living beings.
