That Subtle Essence!

"Bring me a fruit of that Banyan Tree."
"Here it is, venerable Sir."
"Break it."
"It is broken, venerable Sir."
"What do you see there?"
"These seeds, exceedingly small."
"Break one of these, my son."
"It is broken, venerable Sir."
"What do you see there?"
"Nothing at all, venerable Sir."
The father said: :That subtle essence, my dear, which you do not perceive there - from that very essence this great Banyan arises. Believe me, my dear, Now, that which is the sublte essence - in it all that exists has its self. That is the True. That is the Self. Thou art that, Svetaketu.
