Human exists, lives, grows, moves, acts, and develops in cosmos together with his neighbours. There have been so many multidimensional problems and challenges that humanity faced and experienced during humanity existence and life-journey in cosmos.
It is essential that human knows the truth of his essence totally, integrally and clearly for his existing, living, growing, acting, and moving truly, best, most valuably, most meaningfully, totally, and maximally.
Because it is from and of human essence, all human acts of existing and living come. Abandoning or not knowing this principle and key totally, integrally, essentially, and wholly, human may get into real principal, continual, and sequence of problems.
