Hi msjoleary,
For myself, non judgement has always been a trigger that moves me to unconditional love. It very well may be related to my own accumulative practice, past and present, regarding 'why'! My first experience of unconditional love was tied into a practice of non judgement. It was a powerful experience, so that association is there for me. I don't go to judging myself judging myself. Non judgement and judgement are opposites that move me to very different places.
If I am in a state of reflection,not emptiness, where something has come up, I find the concept of non judgement useful. It does start as a concept for me, or remembering, and quickly shifts to a higher experience. Some thoughts seem like random pictures connected to nothing, some seem familiar, and connect to deeper held emotions. Going back to the focus of a meditation or emptiness certainly moves you in the right direction and works. I am not advocating non judgement as a different technique to employ in anyones meditation experience. More a sharing of my own experience and what I employ related to brain chatter. There are times where I am sitting with myself, feeling something, thinking things relative to that. It is more in that particular place, that I instinctively shift, from non judgement, to remembering(truth), to self compassion, then back to my meditation. It can be a very brief instant of moving through something.
I wanted to clearify that I don't speak of non judgement, with an association of that, to then experiencing judgement. It has not been my experience.
love,
gallen
