Towards spiritual enlightenment you have to understand that enlightenment is not a pre-existent, that is fixed for ideal people and unchanging for all human beings in all times.

I believed on the idea that all things are impermanent and that all things are interdependent. The impermanence that must be emphasized is human nature changes as culture interests and needs change. So the idea is about, what is admirable and what is good in life.

Enlightenment is not fixed. What was enlightenment a thousand years ago is not the enlightenment of today. Enlightenment is also not supernatural. The way toward it will not grant omniscience. They also wrong for a perspective that "The holy" separate from the others. It's not an another world image of excellence. It will going bad when the idea of enlightenment upon an unreachable pedestal and will discourage you from the path. Realize that enlightenment is attainable. And that the way toward it is personal.
