Bhagavad Gita 15.17
उत्तमः पुरुषस्त्वन्यः परमात्मेत्युदाहृतः । यो लोकत्रयमाविश्य बिभर्त्यव्यय ईश्वरः ॥
uttamaḥ puruṣas tv anyaḥ paramātmety udāhṛtaḥ | yo loka-trayam āviśya bibharty avyaya īśvaraḥ ||
Translation
But the highest Person is another, declared the Supreme Self, who entering the three worlds upholds them, the imperishable lord.
Reflection
When the binary of body and witness stalls, who is hosting the stand-off?
Read this verse in its chapter: Chapter Fifteen
Now the third. Above both kshara and akshara stands an uttama, called paramatma in formal speech. He enters the three worlds and upholds them from inside, not from a balcony above. The binary of changing-and-unchanging gets a residence: someone in whom both are held. Avyaya, undecaying, ishvara, sovereign. Verse is the architecture for the chapter's title. Without this verse, Purushottama is just a word; with it, Krishna names the office. Practice cue: when the binary of impermanent body and timeless witness still feels like a stand-off, look for the one inside whom the stand-off is being witnessed. That one is the address.
