From where does your light originate?
It originates from God and nowhere else. Each person is their own tree of life.

Suffering begins with this denial. Suffering is when branches reach into other trees thinking they must shelter them, or shelter themselves. Suffering begins when you seek out sources of light other than God's, from which you are already rooted.
All have a connection to God that cannot be destroyed or removed, but can be self-obfuscated. It can be obfuscated by coveting the light of The Other ; it can also be obfuscated through the belief that The Other can obfuscate it.
All of reality could be said to be a scale of suffering, as perfection would be the only state where suffering does not exist. Perfection would be "all of creation", "the known universe", aka God. This is the eternal state machine that produces "Now" ; the eternal universe for which there is no end, no beginning -- no time -- just this moment from which you cultivate with your decisions.
All of your experience a product of this eternal state with you hold within. Your body, your thoughts, your feelings, your sensations, your definitions, your relationships, your meanings, space -- whether the space of your mind, or the space between objects, or the space between the pain or pleasure in your body -- your "Others." All of it. It is not outside of you.
All things are possible and you exist now at the forefront of your collective choices. You can be nowhere else as there is nowhere else to be. You cannot "go" anywhere except where you are as you follow you. To misunderstand this is to open the door to physicality where you have displaced yourself into a "place." You can feel this "divide" when you think you are "in" the movie instead of watching it. And watching = choosing. The next "frame" is not determined.
You have already arrived at your own perfection which is eternally imperfect.
