We use this phrase quite a lot, but in Dzogchen there is no ‘letting go’ of thoughts. In recognition, thoughts naturally dissolve. We don’t have to do anything. When rigpa is present, grasping isn’t. When grasping is present, rigpa isn’t.
I sometimes worry that I need to be doing more when just sitting. I find myself constantly returning to the awareness of awareness and wondering what to do with it – and there is the trap 😉 There is nothing to do. There is nothing to let go of. There is merely spacious awareness.
The cat knows. Be cat-like.
