Who are you?
The body person is one of the many forms of the universe mind. The ‘I’ became the many hence the all of the three dimensional world we see. The universe mind is made of form, time and space.
What is god?
God is the innermost formless substance free from seperation (form, time and space).
When we say innermost substance it is the essence before dreaming and waking and yet it is the all.
