This is definitely the way to go but following the concept of imagistic experiences I doubt this can easily be taught or applied in therapy. This is what Sands referred to as 'Symbolism'. What you have done works for you because it has a deep meaning and emotional value for you. Teaching a stranger 'just do this and that' who has zero connection and emotional investment in those practices is doctrinal and thus doomed to fail. You gotta experience it first-hand.

So teaching and helping others to reach such state is not trivial and difficult to pull off in reality. Let's face it, most people aren't able to pull themselves out of the swamp by their own hair as you did. They need extrinsic motivation but this must come from dear and respected individuals, not random therapists looking at their watches to see when the session is finally over so they can put you on psychopharmaca and send you home. This is why many forms of those scars and mental illnesses are virtually unknown in tribalist societies with excellent social cohesion. We need shamans, not therapists.
