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.

Knowledge cannot be separated from a certain way of life which becomes its living manifestation. To acquire mystical knowledge means to undergo a transformation; one could even say that the knowledge is the transformation.

Mystics understand the roots of the Tao but not its branches; scientists understand its branches but not its roots. Science does not need mysticism and mysticism does not need science; but man needs both.

Modern physics had shown that the rhythm of creation and destruction is not only manifest in the turn of the seasons and in the birth and death of living creatures, but is also the very essence of inorganic matter. For modern physicists...Shiva's dance is the dance of subatomic matter.

Shallow ecology is anthropocentric, or human-centred. It views humans as above or outside nature, as the source of all value, and ascribes only instrumental, or 'use', value to nature. Deep ecology does not separate humans - or anything else - from the natural environment. It does see the world not as a collection of isolated objects but as a network of phenomena that are fundamentally interconnected and interdependent. Deep ecology recognizes the intrinsic value of all human beings and views humans as just one particular strand in the web of life.

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.

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.
