Acharya Prashant explains that the definition of cheating depends entirely on the plane upon which a relationship exists: physical, mental, or spiritual. In a purely physical relationship, the contract is based on the mutual exchange of pleasure and bodily commitment. Consequently, physical infidelity is seen as a total destruction of the relationship because the body was its only foundation. If a person is absolutely offended by physical cheating, it indicates that their relationship was fundamentally physical, regardless of how they might have labeled it with fancy names or romantic ideals.
