Fritjof Capra on the Unity of All Things, One
Problem of the One and the ManyBoth Indian and Greek Philosophy originated from the correct realization that there must be One thing that is common to, and connects, the Many things, and further that Motion (activity, change) was also central to existence.
Brahman is the unborn (aja) in whom all existing things abide.
The One manifests as the many, the formless putting on forms. (Rig Veda ~ 1200 B.C.)
