Who is speaking and story frame
यस्त्वां विसृजते मर्त्य आत्मानं प्रियमीश्वरम् ।
विपर्ययेन्द्रियार्थार्थं विषमत्त्यमृतं त्यजन् ॥ ४२ ॥
yas tvāṁ visṛjate martya
ātmānaṁ priyam īśvaram
viparyayendriyārthārthaṁ
viṣam atty amṛtaṁ tyajan
That mortal who rejects You — his true Self, dearmost friend, and Lord — for the sake of sense objects, whose nature is just the opposite, refuses nectar and instead consumes poison.
