Excerpt from the book: “I entered the dense layers of some nebula and slowed down again when I saw ahead of me a huge orange-red ball, in places covered with white spots and as if bordered by a yellowish halo. It’s even surprising that I, being just a subtle thought, could observe the Galaxies themselves in their power, and the space filling them. As if there were no barriers to the movement of thought, its observation and knowledge of the world.”
