Its about a glass in which some water was poured and then people were asked about what they see?A half filled glass or a half empty glass? The response defined the person as an optimist or a pessimist. A well known and interesting interpretation. I was fascinated by it for a long time and was happy it was half filled for me. But something struck me today. Just flashed. The glass is full. Half with water and half with air. The emptiness is but illusory because eyes don’t perceive the gaseous mixture. This is science and yet I see some flash of thought in that. Nothing is truly empty . Its but our failure to identify the filler or may be a yearning for something we want more than what already is. The truth is true emptiness cannot exist for long. It would then create a vacuum which would frantically try to absorb itself with whatever comes it’s way!
