This part really hit me:

But accepting something is not necessarily becoming as-one with something. You can accept something is happening at a mental or emotional level. In order to become as-one with that situation, is to feel deeply into any reactivity about it - feel intimately internally to your inner response. Then to surrender through.

I realise I'm doing this, trying to accept things on a mental and emotional level and I can see now how it's the ego trying to build in acceptance of limitations. Except it can't really, so on a deeper level there is no real letting go and the same cycles keep going. Thanks for this reflection!
