When you asked who is seeing. your act of seeing was stopped and when you asked Who am I? Something disappeared into your heart?? What if you could stay in that thoughtless space for sometime???That’s when you will know all is illusion!
Thinking ( seeing) is attachment based on ignorance! Once your question is raised it stops ( detachment) and who am I? Sends the I thought back to the supreme source!
With repeated practise you can train your mind to be free of attachment!
Observation is the nature of the higher self!
Thinking = attachment
Observing = detachment
