First of all, what is an idealistic consciousness?
I consider a consciousness that feels fundamentally compelled to think in terms of possibilities rather than limitations to be an idealistic consciousness. When idealistic consciousness is repeatedly confronted with a situation that it experiences as limiting, it continually seeks space to cope with the situation. It therefore thinks and acts in a way that is already future-oriented: "Once I'm out of this, I'll do 'this,' so what are the paths and steps needed to get there as quickly as possible?" It learns from each new situation and uses all this information to broaden its capacity. But it also regularly reflects on its own experience to feel and process it.

Idealistic consciousness in a hopeless situation.
The longer the struggles and unpleasant situations persist, the greater the tolerance for unpleasantness becomes. At some point, the unpleasantness becomes so inhuman or hopeless that consciousness can no longer act towards the future. In my experience, this is when it seeks space beyond human limitations. It learns to zoom out in a way that limits the struggles and unpleasantness to its own life. In this situation, an idealistic consciousness is forced to think beyond itself. It begins to view itself as one small part of a much larger universe. And learns to zoom out in a way that subordinates the human, such as ego, emotions, desires, expectations, etc., to the bigger picture of our existence as humanity in this world. It learns to view itself as a necessary, temporary being that needs to be lived through, but whose surrounding context doesn't matter much. Things like money, many friends, and the need for space, or a lot of recognition, become increasingly unimportant. And what remains is a task/assignment felt deep within.

"There's a reason my life has shaped me this way, and being able to share this awareness with others is my humble contribution to this world that will last much longer than I do. For I am but a grain of sand in the desert, and the desert is but a plain of sand on a vast earth, and the earth is but a tiny sphere in the cosmos. It is never the most important thing what kind of life one grain of sand has, one grain of sand does not make a desert".
