Only through discussion beginners and intermediates gradually become aware what is what. Only after they have been through the inquiry, analysis and reasoning they ready for journey towards non-duality. When one say all these are imagination, he wants to attain to a state when he can negate the whole illusion--one thorn pulling out the other thorn and both thrown away--that is the whole of secret , and hence seeker has to think deeply before commenting on the base of accumulated waking or dream centric knowledge which always misleads.
