Acharya Prashant addresses the issue of cheating in relationships by first defining it in its most common physical sense, which is often avoided in polite conversation. He argues that if a marriage or relationship is founded solely on physical attraction and the body, it is built on a shaky and vulgar foundation. Such an arrangement, which essentially promises exclusive sexual access, is destined to fail because the human body and its natural instincts are inherently promiscuous. He explains that the pain of cheating is the natural punishment for entering into a relationship based on physicality rather than spiritual depth.
