Here are some quote which speak to miracles or miraculousness being something that does not depend on perception, suggesting that miracles are not "shifts in perception", but rather that miracles are creative expressions of love which can *produce* shifts in perception.
This is because MIND and PERCEPTION are two different levels. Mind was mind before perception was introduced. Perception is a layer of interpretation on top of the mind. Miracles come through the mind from God's mind, as expressions of MAXIMAL LOVE, and CAUSE perception to change to line up with the mind. "Miracles are a corrective device introduced into the MIND by me." But the miracle is occurring and coming FROM the mind-level of love, producing secondary EFFECTS in the perceptual realm.
Decoupling miracle mindedness from perceptual shifts, and seeing the shifts as "effects" of miracles, allows us to see that you can be consistently miraculous when your perception has nothing left to shift. Simply because miracles originate BEYOND PERCEPTION, which is why they can CORRECT it.
This is also why we become MORE miracle minded and more miraculous and more able to constantly perform miracles, as we uncover love and our mind lines up with God's will and power. Being miraculous isn't temporary. We are a PERMANENT MIRACLE and miraculous creation is our nature. Which is why "Miracles are supposed to be happening all the time. When they aren't, something has gone wrong."
"12a. Miracles are thought-creations. Thought can create lower-order or higher-order realities. This is the basic distinction between intellectualization and thinking. One creates the physical, and the other the spiritual, and we believe in what we create."
"23 ... YOU are a miracle. God creates only "that which, or one who, is of surpassing excellence or merit". Man is capable of this kind of creation, too, being in the image and likeness of his own Creator. Anything else is only his own nightmare, and does not exist. Only the Creations of Light are real."
"Prayer is the medium of miracles, not because God created perceptions, but because God created YOU. At the beginning of this course, we said that YOU are a miracle. Therefore, the miracle worker is a miracle NOT of his own creation."
"Each *Soul* knows God completely. This IS the miraculousness of the *Soul*. The fact that every each *Soul* has this power completely is a fact that is entirely alien to human thinking, in which if any ONE has everything, there is nothing LEFT."
"9. Miracles are a kind of exchange. Like all expressions of love, which are ALWAYS miraculous in the true sense, the exchange reverses the physical laws."
"4. All miracles mean life and God is the giver of life."
"27. A miracle is a universal blessing from God through me to all my brothers."
"38 - The Holy Spirit is the mechanism of miracles."
"43 - Miracles arise FROM a miraculous state of mind, or a state of miracle-readiness."
