The author's purpose is to demonstrate the similarities in the quantum/relative world view and the worldview of Eastern mysticism. Page numbers are for the 25th anniversary edition of the book published by Shambhala in 2000.
...the various schools of Eastern mysticism... all emphasize the basic unity of the universe... The highest aim for their followers--whether they are Hindus, Buddhists or Taoists--is to become aware of the unity and mutual interconnection of all things, to transcend the notion of an isolated self and to identify themselves with the ultimate reality."
The most important characteristic of the Eastern worldview--one could almost say the essence of it--is the awareness of the unity and mutual interrelation of all things and events, the experience of all phenomena in the world as manifestations of a basic oneness. (p. 131)
Capra mentions multiple times that Eastern philosophy sees the world as inherently unified (hence, universe) and dynamic. All separateness and all static objects are an illusion. In the subatomic world, the particles that make up the world around us are always in flux. Many of the features of these particles, for instance, cannot be known for certain as the quantum world has a basic indeterminateness to it. He contrasts these viewpoints with a mechanistic view--which he finds is the predominant Western worldview--that sees the world as made up of individuals objects and the forces that these objects respond to (or perhaps can influence as in the case of a human).
Rational knowledge is derived from the experience we have with objects and events in our everyday environment. It belongs to the realm if the intellect whose function is to discriminate, divide, compare, measure and categorize. In this way, a world of intellectual distinctions is created; of opposites which can only exist in relation to each other, which is why Buddhists call this type of knowledge 'relative'. (p. 27)
Because our representation of reality is so much easier to grasp than reality itself, we tend to confuse the two and take our concepts and symbols for reality. It is one of the main aims of Eastern mysticism to rid us of this confusion. (p. 28)
It is important to realize the difference between the mathematical models and their verbal counterparts. The former are rigorous and consistent as far as their internal structure is concerned, but their symbols are not directly related to our experience. The verbal models, on the other hand, use concepts which which can be understood intuitively, but are always inaccurate and ambiguous. They are in this respect not different from philosophical models of reality and thus the two can be very well compared. (p. 33)
At the atomic level, then, the solid material objects of classical physics dissolve into patterns of probabilities, and these patterns do not represent possibilities of things, but rather probabilities of interconnections. Quantum theory forces us to see the universe not as a collection of physical objects, but rather as a complicated web or relations between the various parts of a unified whole. (p. 138)
