Bhagavad Gita · Raja Vidya Raja Guhya YogaChapter 9, Shloka 19 (9.19)

Shankaracharya. Tapāmi aham ādityo bhūtvā — I give heat by becoming the sun; nigṛhṇāmi … aṣṭabhiḥ māsaiḥ, punaḥ utsṛjāmi prāvṛṣi — holding it back for eight months, I send down the rain again in the rainy season; amṛtaṃ caiva devānāṃ, mṛtyuś ca martyānām — the nectar of the gods, the death of mortals; sat … asat ca … na punaḥ atyantam eva asat bhagavān — but the Lord is not "non-being" (non-existence) in the absolute sense; kārya-kāraṇe vā sad-asatī — or being and non-being mean effect and cause.

Acharya Ramanuja. Amṛtaṃ ca eva mṛtyuḥ ca yena jīvati loko yena ca mriyate — that by which the world lives and that by which it dies — both are me; sad yad vartate, asad yad atītam anāgataṃ ca — being = what exists now, non-being = what is past or yet to come; sarvāvasthāvasthita-cid-acid-vastu-śarīratayā tat-tat-prakāraḥ aham eva — conscious and non-conscious things in every state are my body, so it is I in every form.
