That was a phrase that came up in an online course I am taking. The Heart Rhythm Meditation class is a form of meditation that develops heart capacity and energy. I had two reactions to the statement. The first one was, "What a wonderful way to drop into acceptance" when applied to anything beyond the present moment. If I don't mind what happens, then it means that I'm flexible and open to the outcomes and the reality that I'm in. It means that I"m able to go with the flow and allow for a world beyond my own nose!
Now the flip side of that of course, is the ol' doormat syndrome. Something I've been intimately friendly with over the course of many years. Fortunately that side of me has grown and developed to a less passive state but its been lots of work becoming conscious and aware of fears, obstacles and other things that get in the way of standing up for ourselves. So the "Ohhhh I don't mind what happens," could be a danger flag that one isn't paying attention and will likely get smashed by some errant bulldozer. A small voice after being completely flattened weakly saying, "Hey - I think I do MIND that you're stepping all over me!" Its funny to have both perspectives going on with one statement.
How do we know which one we are operating from? Dropping into the sensations of our body can elicit the truth. It may be that both perspectives are operating at the same time. One of the things that is helpful for me is to think it through to an end, if possible. There are always scripts available - ones that just are about ourselves without anyone else involved - others are all about how we think another person will think or feel. We can have great fun with projection. But it rarely works because we don't ever know how another person is going to react or feel. Its their business. Our business to stay on our side of the street and assess whether we really don't mind what happens - or whether its a statement of complacency and resignation.
