Looks like I'm getting somewhere! I have reached MAP Chapter 5, and believe I can reach light trance. The key was to improve my ability to empty my mind, as well as feeling the downward movement, instead of just visu/verbalising. It was another 'aha erlebnis', like 'ha, is that what they call trance, I have experienced this before, but never knew what is was'. So, now I know what to look for, I guess I can go deeper and deeper...
