Acharya Prashant explains that one's definition of cheating reveals the plane on which their relationship exists. He states that relationships can broadly exist on one of three planes: spiritual, mental, or physical, and cheating is possible on all three. Cheating is simply a violation of the contract that forms the basis of the relationship. A relationship on the physical plane is a contract for mutual physical pleasure. The commitment is to provide an uninterrupted and secure supply of this pleasure. Therefore, physical commitment means being available when the other person needs your body. Cheating on this plane is a violation of the physical contract, such as being with someone else. If a relationship is 100% about the body, then physical infidelity means the relationship is 100% destroyed. The speaker notes that if one is absolutely offended by physical cheating, it implies the relationship itself is absolutely physical, like that of animals. A mental relationship is based on an exchange of emotions and a romantic agreement to boost each other's egos. The contract is to say and do things that please each other mentally. Cheating on this plane involves offending the partner's ego, for instance, by saying something unpleasant or being physically with someone else, as both are offensive to the ego. The speaker points out that many relationships are fundamentally animalistic and physical, but are covered up with fancy names like 'love' to make them seem more acceptable. In a spiritual relationship, two people are together not for each other's sake, but for a shared higher goal, which he refers to as "that something"—be it Truth, liberation, or joy. The primary commitment is to this shared goal, not to each other. In this context, cheating is being disloyal to that higher purpose. In fact, becoming attached to the partner is considered cheating, as the focus should be on the shared destination. The role of a partner in a spiritual relationship is to help the other move towards the goal, even if it requires pushing them or saying things that are not pleasing to the ego.
