I love this thread. Recent explorations have taken me deep into it. The wonderful initial slipperyness of it invites less efforting and then when the inner landscape naturally settles for long enough there's a sense or knowing where 'you' are no longer form or thought where connection beyond beingness is . My experiences are very atuned to your explanation Open...think Buddhism call it 'no mind' & it is appropriately also known as 'Open' ground.
Thank you, the clarity is so appreciated.
