यस्तमसि तिष्ठंस्तमसोऽन्तरः, यं तमो न वेद, यस्य तमः शरीरम्, यस्तमोऽन्तरो यमयति, एष त आत्मान्तर्याम्यमृतः ॥ १३ ॥
yastamasi tiṣṭhaṃstamaso’ntaraḥ, yaṃ tamo na veda, yasya tamaḥ śarīram, yastamo’ntaro yamayati, eṣa ta ātmāntaryāmyamṛtaḥ || 13 ||
13. He who inhabits darkness but is within it, whom darkness does not know, whose body is darkness, and who controls darkness from within, is the Internal Ruler, your own immortal self.
