I think that passage I linked says, "Be here now."
A few of my dysfunctional thought processes which I work on are, catastrophizing, anticipating (expectations), worrying, jumping ahead. I often try to anticipate the next thing in order to somehow control the next crisis. If I stay in the moment - this exact moment - I can stay at peace. I've let go of the past - but I still think I have some control over the future...even if it's something as simple as a conversation with someone. I think this is pretty common with trauma and abuse victims. I want to protect myself from discomfort, discontent, dissention, disagreement.
I hope to learn to be comfortable, content, accepting and in agreement with the Universe - exactly like it is. One day at a time.
It's a process. A daily discipline.
