If all the world’s religions, spiritual practices and ways of self-improvement pursue the main goal of self-actualization, gaining integrity and achieving internal harmony, i.e. help to gain the awareness of something bigger than the material world in every manner one can think of, does not this mean that the mankind has lost the connection with the «other side» through one’s own fault?
The causes and consequences is yet another issue to discuss. Perhaps, it is due to our «heavy» three-dimensional physical world. Well, it’s heavy in relation to the mental world.
And after all, we still, probably, have a door to enter this world of awareness, the one that is «here» referred to as the superconscious.
And the door is our dreams.
