Acharya Prashant explains that the mind is a sacred space that should be kept clean, much like a temple. When one hates another person, they inadvertently keep that person in their memory, effectively making them an object of worship within their own mind. He suggests that true hatred, in its purest form, would actually manifest as forgiving and forgetting. By continuing to hate, an individual maintains a strong relationship with the person who deceived them, preserving their memory because their own level of consciousness has not changed since the relationship began.
