Within Kum Nye there are three levels of relaxation. I’ve likely mentioned this. The first is superficial (but still quite nourishing), where you just calm down. It is what you feel after a good massage or a long bath.
The second is Kun Zhi, which if memory serves means in Tibetan “solid ground”. This term makes sense to me now. In your practice, it is like you are drifting slowly down in the water, and you reach bottom, and you stay there a long time. It feels like the bottom. It feels solid. Then one day it dissolves and you keep going, and as it dissolves, you feel all the bad stuff, all the ego, all the darkness, all the evil, the hidden rages, the compulsions, the shit.
And of course they don’t disappear, but their work depends almost entirely on subterfuge, on hiding, on not being seen, on operating under the radar. Once you can see them, you can name them, and you can dissolve them as they arise. This capacity is, itself, the beginning of the capacity for conscious growth, for learning.
This is the third level, the one at which within this particular practice “meditation”, per se–concentration–becomes possible. It is pointless until then, or largely so.
