In Chapter 11 of The Gita, in answer to Arjun’s request, God gives Arjun a divine eye. Thus empowered, Arjun sees God in His powerful beauty, with multiple faces, eyes and mouths, and with magnificent jewels weapons, garlands and clothes. His form is covered with fragrant pastes and glows with the light of a thousand suns.
Arjun perceives the entire endless universe and contained within God and he sees God without beginning, middle or end. He sees nothing but God’s overwhelming brilliance.
The verses describing this vision of the Lord put into words the emotions and thoughts of believers and devotees who try to imagine and explain their certainty about the existence of a benevolent Creator and Preserver to whom they are devoted. The descriptions bring to life ideas that are beyond description or explanation but self-evident to many.
In my opinion, the notion of God evidences a truth that is real because it lives in human hearts and minds though it cannot be quantified or qualified in expressions or images. Human notions, howsoever inexplicable, are powerful. They do not arise from nowhere and cannot be dismissed as nothing.
