As you think so shall you be! Since you cannot physically experience another person, you can only experience them in your mind. Conclusion: All of the other people in your life are simply thoughts in your mind. Not physical beings to you, but thoughts. Your relationships are all in how you think about the other people of your life. Your experience of all those people is only in your mind. Your feelings about your lovers come from your thoughts. For example, they may in fact behave in ways that you find offensive. However, your relationship to them when they behave offensively is not determined by their behavior, it is determined only by how you choose to relate to that behavior. Their actions are theirs, you cannot own them, you cannot be them, you can only process them in your mind.
