The world is a construct of our sensations, perceptions, memories. It is convenient to regard it as existing objectively on its own. But it certainly does not become manifest by its mere existence.

The sensation of colour cannot be accounted for by the physicist's objective picture of light-waves.

Vedanta teaches that consciousness is singular, all happenings are played out in one universal consciousness and there is no multiplicity of selves.

The world is given to me only once, not one existing and one perceived. Subject and object are only one.

Nature has no reverence towards life. Nature treats life as though it were the most valueless thing in the world.... Nature does not act by purposes.

Quantum physics thus reveals a basic oneness of the universe.

The multiplicity is only apparent. This is the doctrine of the Upanishads. And not of the Upanishads only. The mystical experience of the union with God regularly leads to this view, unless strong prejudices stand in the way.
