Bhagavad-gītā As It Is · Text 15.17
The Supreme Person beyond fallible and infallible
उत्तम: पुरुषस्त्वन्य: परमात्मेत्युदाहृत: ।
यो लोकत्रयमाविश्य बिभर्त्यव्यय ईश्वर: ॥ १७ ॥
uttamaḥ puruṣas tv anyaḥ
paramātmety udāhṛtaḥ
yo loka-trayam āviśya
bibharty avyaya īśvaraḥ
Besides these two, there is the greatest living personality, the Supreme Soul, the imperishable Lord Himself, who has entered the three worlds and is maintaining them.
