Abstract
It seems to the author that, though it is possible to reach an explanation of consciousness, there is no direct way for us to go. In other words, the author believes that, only through a detour, through an understanding of everything outside mind, we may and can and will finally reach an understanding of those inside.
The author tries in this article to discuss some details of such a detour, first from the understanding of Being and being, universe and life, organism and human, and finally to the understanding of the mind and the mystery of our consciousness.
Here, to understand Being is the core activities of the whole detour, and there the being is understandably the source and the nature of life and consciousness.
