Acharya Prashant explains that the definition of cheating depends entirely on the plane upon which a relationship exists: physical, mental, or spiritual. In a physical relationship, the contract is based on the mutual exchange of pleasure and bodily commitment. Cheating at this level is a violation of that physical contract, such as one partner being unavailable or sleeping with someone else. If a person is absolutely offended by physical infidelity, it indicates that their relationship was fundamentally and entirely physical, regardless of how they might have labeled it. In a mental or emotional relationship, the agreement is to provide mutual ego-satisfaction and romantic validation. Cheating here occurs when one partner stops pleasing the other's ego or says something that causes mental offense. Acharya Prashant notes that many relationships use emotional rituals as a mere alibi or face-saving mechanism to reach the physical objective. He points out that if a long-term relationship collapses instantly due to physical transgression, it proves that the bond was never more than sexual, despite any 'fancy names' or self-deception used to cover its animalistic nature. Finally, he describes a spiritual relationship where the primary commitment is not to each other, but to a shared higher goal, such as truth or liberation. In this context, cheating is defined as being disloyal to that higher purpose or becoming attached to the partner instead of the goal. In a spiritual bond, partners act as co-passengers who push and nudge each other toward realization, often going against each other's egoistic wishes. He concludes that most human relationships remain at an animalistic level because humans are evolutionary immigrants from the jungle who often hide their basic biological intentions behind complex social courtship.
