Space is a fundamental concept in Buddhism. As the ground of existence, it is one of the very few things that is eternal and unchanging. Contemplation of space is.. well spacious and mind expanding. Whether we do it in silent meditation, or with Saturn 5 rockets, or just by trotting along a forest path, the urge to explore space is always there. It is truly fundamental.
In the science of quantum mechanics, the fundamental nature of space becomes apparent. Merely by positing a space composed of three dimensions and something existing in it, wave functions can be deduced, particle interactions elucidated, indeed the whole of physics falls out out of this single thing, space. Even so, we don't really understand space, we can't say what it is made of, we can't say where it is, and we can say almost nothing about its properties. What is needed is direct knowledge, insight. And the Space Sphere has that knowledge.
The Space Sphere is the ground of non-dual knowledge. By drawing on the wisdom of the Space Sphere, we can gain a deep and intuitive understanding of space, see why it drives us to explore, know how it shapes the very processes of thought itself. But first, we need to access the Space Sphere. At one time this would mean spending years in retreat, perhaps decades. But I have discovered an unbelievable video that some genius has posted that takes you into direct contact with the Space Sphere. Basically, the knowledge of the Space Sphere is now freely available on the internet.
So without further ado, here's the link.http://www.youtube.com/watch?v=BVn1oQL9sWg
