Bhagavad Gita: Chapter 2 - Verse 29

A wonder for all

Ascharyavatpashyati Kaschidenam Ascharyavadwadati Tathaivachanyaha
Ascharyavacchaina Manyashrunoti Shruthwapyenam Vedaa Chaiva Kaschit
Some have a glimpse of the consciousness manifesting itself and wonders about it. Some speak of Him as a marvel and some hear Him as a marvel. Yet, none know about Him, despite, seeing, speaking or hearing.
Consciousness is so subtle that it cannot be fathomed with the sens organs, but always keeps one in a state of wonder.
