ज्योतिषामपि तज्ज्योतिस्तमस: परमुच्यते | ज्ञानं ज्ञेयं ज्ञानगम्यं हृदि सर्वस्य विष्ठितम् ॥18॥
jyotiṣhām api taj jyotis tamasaḥ param uchyate jñānaṁ jñeyaṁ jñāna-gamyaṁ hṛidi sarvasya viṣhṭhitam
jyotiṣhām—in all luminarie; api—and; tat—that; jyotiḥ—the source of light; tamasaḥ—the darkness; param—beyond; uchyate—is said (to be); jñānam—knowledge; jñeyam—the object of knowledge; jñāna-gamyam—the goal of knowledge; hṛidi—within the heart; sarvasya—of all living beings; viṣhṭhitam—dwells
That is the Light even of the lights; It is spoken of as beyond darkness. It is Knowledge, the Knowable, and the Known. It exists specially in the hearts of all.
