What you call as Me, is nothing but a body and ideas. Nothing more. This body is also nothing other than bones and accumulated amount of foods and energy. Lastly, these ideas are nothing but what you were able to pick up and gather so far over the period of your existence. Then my question is, What then is Me? Have you taken time to know this very simple thing.
Let's assume that today, you lost your memory and you no longer eat food, what then is you is nothing. You're nothing but rather food and ideas. Take a moment to study the life of a mad person, whose thinking faculty is impaired or let's say has just lost just a little part of his ideas/mind/ thinking ability, his existence becomes of no definitive purpose, no how much more a person with no ideas nothing in the brain?
This life is deeper than you think.
