> This brings me to a critical issue: the side effects of meditation. One could argue that a strategy consisting of closing one’s eyes when facing conflicts, in escaping from problems rather than solving them, is perhaps a suboptimal strategy.
In Dzogchen meditation (which is his main practice), one does not close one's eyes or always sit in a special posture. It is engaged with real life. There is no "escaping" of any sort whatsoever. Thoughts arise as they normally do; it is only the method of dealing with them that differs (both from our usual habits and from other approaches like mindfulness as it is normally understood).
