Those who often bring about your negative emotion are ostensibly the cause of your suffering, in fact, you made a deal with them before you incarnated into this life, your encounter with each other in this life is absolutely no coincidence, without knowing it themselves, they enter your life in order to assist you to transcend your suffering and eventually achieve your spiritual growth, well, of course, you do the same for them.
Once you understand they are here with you for a divine reason, you will no longer blame them for what they are, you will become peaceful from within, you will be able to open your heart to accept and forgive whatever seem to come against you, for you now realize that it is necessary for you to experience every situation that can happen to you during your lifetime, indeed all is perfect for you no matter what appeared otherwise.
