Abhijit Naskar said this quote

Beauty is an illusion, created by Mother Nature to drive the human species in the path of reproduction. In reality, beauty is irrelevant to human life, especially in a relationship. What you today perceive as beautiful and special, over time, becomes not so special. That’s how the human brain works. It is not beauty that keeps a relationship alive, it is attachment. Without attachment, a naked body is merely a lifeless sex toy.
