In the ego's physical world, the form and the function of something are fixed.
You can use a pair of scissors to cut paper, but you can't use a pair of scissors to alleviate your hunger. You can use a screwdriver to screw in a screw, but you can't use it to water your crops. You can use a toilet to flush some poop, but you can't use the toilet to cook your dinner (hopefully).
Physical objects, forms, have a fixed function. This is because the ego is a fixed device. It is something you made with a single FUNCTION, and that function is fixed. Its purpose is specific and limited and unchanging. It was made as a device to oppose God. It was made to "see" God from a completely opposite vantage point and perceive God as though God is false, and that therefore death is true.
It was designed to fulfill that function, and just like any other "tool" that you use, it is just another tool which has one function and one function only. You can't turn it into something else and you can't make it do things it was not designed to do. Because the ego is "this world", forms in this world are fixed in their function also, and can only be used according to their properties or functions.
Your only choice with the ego is whether you pick it up and USE it, or whether you put it down and stop using it. You cannot change it into the truth. You cannot bring it with you into Heaven. You can't transform it to make it more spiritual. You can't convince it that God's truth is true. You can't make it listen or change its ways. It is a fixed-function tool that only does one thing and never will do anything else.
When you are identified with this tool and think it is your SELF, you will attempt to change IT whenever you are attempting to change YOU, and it can't change. It will object and see this as an attack and a threat. It will produce an ego rebound, because it does not want to and cannot wake up, and it cannot see the truth or understand it or accept it. The part of you that is still USING it does not want and cannot accept the truth "through" it, and that part of you will see your attempts to awaken as an attempt to destroy yourself. i.e. to destroy your illusory "function".
The only real choice for "becoming more spiritual" is to drop the ego and stop using it, stop listening to it, stop identifying with it, stop trusting it, stop believing it, stop living through it, stop perceiving with it, and stop trying to make it be real. You cannot keep it. You have to let it go. To surrender everything that it tries to do. And that also means giving up ITS illusory spiritual path which is nothing more than exchanging one set of illusions for another.
To become more aware of the truth about you, you need to bring into question whether the ego you trust is really the truth, discern that it is false, recognize it as false, and decide to accept the real truth as it is without your ego filtering it. The ego plays no part in that, and it's purely your decision to realize that your false identity is not your true self, that you are more than you appear to be, that you are not anything the ego describes or judges, and that your true nature has not been changed by your use of the ego device.
Your awakening then is a shift in IDENTITY, given that who you thought you were is not really who you are, and is not the whole of who you are. You are more than you are aware of. You are more than the ego sees. You are more than your body. You are more than a separate person split off from everyone else and from the universe. And you are more than this universe. You are the Son of God - the singular total full expression of everything God is everywhere.
Lies do not become the truth. Fear does not become reality. Death does not replace life.
