Sri Aurobindo’s Yogic Vision of ‘Electron’ as a Form of Consciousness and the ‘Probability Wave’ of the Quantum Theory
On a very high plane of yogic consciousness, Sri Aurobindo has discovered consciousness to be the ‘fundamental thing in existence’. It is the consciousness which arranges itself to come into the forms of ‘electron, atom, and material existence’. Such yogic discovery comes into the vision of the scientific mind when the scientists working on the Quantum Theory discover a wave which is not...
