"When God created you (in Heaven), He made you part of Him. That is why attack WITHIN the Kingdom is impossible. But YOU made the ego without love, and so it does not love YOU. You could not remain WITHIN the Kingdom without love, and since the Kingdom IS love, you believe you are WITHOUT it (exiled from Heaven). This enables the ego to regard itself as separate and OUTSIDE its maker, thus speaking for the part of your mind that believes YOU are separate and outside the Mind of God. (outside of Heaven in another world)"
"You are safe in God, dreaming of exile (being external to Heaven in another realm)"
"There is no life outside of Heaven (in the big picture). Where God created life, there life must be. In any state apart from Heaven (e.g. planet Earth which is "outside" the Kingdom) life is illusion. At best it seems like life ("life forms, which are not life"); at worst, like death."
"Life not in Heaven is impossible, and what is not in Heaven is not anywhere. Outside of Heaven, only the conflict of illusion stands (planet Earth, all things physical); senseless, impossible and beyond all reason, and yet perceived as an eternal barrier to Heaven (granite block of sin, walls, bodies, forms). Illusions are but forms (all physical forms are an illusion). Their content is never true."
"Attack in any form has placed your foot upon the twisted stairway that leads from Heaven."
This is why the "physical universe" including Earth, which is "the strange world you made", is opposite to Heaven and an idea of being "outside the Kingdom". It was made like a kind of second "dimension", a fake universe, a bubble of spacetime within the Kingdom. Seeming to be made of the idea of exile and separation, it seems "separate from" the Kingdom, and therefore seems like an entirely cut off realm. This is why awakening from the dream of exile MUST take you back OUT of the realm of exile and INTO the Kingdom, which quite literally will seem like traveling to another dimension beyond space and time.
"Heaven remains your one alternative to this strange world you made and all its ways; its shifting patterns and uncertain goals, its painful pleasures and its tragic joys. God made no contradictions. What denies its own existence and attacks itself is not of Him. He did not make two minds, with Heaven as the glad effect of one, and earth the other's sorry outcome which is Heaven's opposite in every way."
This is also why Jesus talks many times about the difference between being "on Earth" and "in Heaven".
"The Holy Spirit is the way in which God's will can be done on earth as it is in Heaven."
"It but acknowledges the Will of God is done on earth as well as Heaven. It unites all wills on earth in Heaven's plan to save the world"
"You have been told that your function in this world is healing, and your function in Heaven is creating. The ego teaches that your function on earth is destruction, and that you have no function AT ALL in Heaven."
"And as it is in Heaven, so on earth."
"Heaven is the dwelling place of the Son of God."
"His will is done because all power is given him in Heaven and on earth."
"As your function in Heaven is creation, so your function on earth is healing. God shares His function with you in Heaven, and the Holy Spirit shares His with you on Earth."
"In Heaven, reality is SHARED, and not reflected."
"You on earth have no conception of limitlessness, for the world you seem to live in IS a world of limits."
"Father, in Heaven it is different, for there, there are no needs. But here on earth the miracle is closer to Your gifts than any other gift which I can give."
"The miracles you do on earth are lifted up to Heaven, and to Him."
"For that is changeless, and has no effects which anything in Heaven or on earth could ever alter."
"Because my feet are on the ground and my hands are in heaven, I can bring down the glories of Heaven to my brothers on earth."
Heaven is a place. Not just a state of mind. It is the reality of the Kingdom. Earth is just part of an illusory world based on the idea of exile, exclusion, separation and death. You can be "on Earth", or "in Heaven", but not both. Either you are aware of being in the Kingdom or you are aware of being in a body.
