Talks with Ramana:
Q: What is this mind?
R: Mind is one form of manifestation of life. A block of wood or a subtle machine is not called mind. The vital force manifests as life-activity and also as the conscious phenomena known as the mind.
Q: What is the relation between mind and object? Is the mind contacting something different from it, viz., the world?
R: The world is ‘sensed’ in the waking and the dream states or is the object of perception and thought, both being mental activities. If there were no such activities as waking and dreaming thought, there would be no ‘perception’ or inference of a ‘world’. In sleep there is no such activity and ‘objects and world’ do not exist for us in sleep.
