The castle of "I" is built on the beach, out of sand. It has no firm rock foundation. It can collapse at any time or get washed away by the incoming tide. This is the ego built castle, a temporary and unsound edifice on the beach. No one knows the true centre of awareness because who is there to know it ? The "who", the person, is just part of the sandcastle on the beach.
