When you can't tell which is which - that's integration.
The quote from Jean - luc, whom I consider one of the most advanced of the Western practitioners, is apt as a to do list (roughly defined) of integration.
The point is that you can be passive or active in your pursuit of enlightenment: there are many practices TO DO which enable integration, or you can stare at the wall for 8 years, which also works.
ChNNR has taught over 100 secondary practices. When you have the transmission of each practice, you can DO these, as appropriate to your circumstances, and get the benefit - integration of the natural mind with activity. Then, with direct experience, the issue / question of integration becomes the famous "one taste" or the "all good", and that is the "integration" beyond words.
The precise problem is that all language is dualistic, and pointing at the non-dual natural state of awareness with terms like 'integration" or "informed by" or "non-dual" which are, in language, intrinsically dualistic, is NOT the same thing as the direct experience of the natural state, which cannot be described in words.
That said, some words are more pointy than others. http://namgyalgarnorth.com/recent-ssi-p ... -by-chris/
Note the mountains and the space between the mountains - now make this the same observation.
