In ordinary life, we are not aware of the unity of all things, but divide the world into separate objects and events. This division is useful and necessary to cope with our everyday environment, but it is not a fundamental feature of reality. It is an abstraction devised by our discriminating and categorising intellect. To believe that our abstract concepts of separate 'things' and 'events' are realities of nature is an illusion.

If physics leads us today to a world view which is essentially mystical, it returns, in a way, to its beginning, 2,500 years ago... This time, however, it is not only based on intuition, but also on experiments of great precision and sophistication, and on a rigorous and consistent mathematical formalism.

The mystic and the physicist arrive at the same conclusion; one starting from the inner realm, the other from the outer world. The harmony between their views confirms the ancient Indian wisdom that Brahman, the ultimate reality without, is identical to Atman, the reality within.

Zen phrase says The instant you speak about a thing you miss the mark.

The more we study the major problems of our time, the more we come to realise that they cannot be understood in isolation. They are systemic problems, which means that they are interconnected and interdependent.

A sustainable human community is designed in such a manner that its ways of life, technologies, and social institutions honor, support, and cooperate with nature's inherent ability to sustain life.
