Gratitude without pressure

I've been thinking about gratitute a lot, and there is so much talk about that in spiritual circles these days. I actually am immensely grateful for so much in my life, but when I get grumpy and am feeling lack instead of abundance, the idea that I "should" be grateful and that I am being "bad" because I feel grumpy, is not so helpful. Today, I found out that actually just sitting down I can contact gratitude by just sort of falling into it....it is there, part of our natural ground. This goes with the idea of basic goodness. That's a concept to which I was introduced through my Tibetan Shambhala practice, which I love because it is so positive -- it is about being in the world in a positive way. Anyhow, it is a relief to know I don't have to work up a whole bunch of energy when I don't have it in order to feel grateful ON TOP of feeling grumpy. Just relax, and bingo: Gratitude! It feels very good. A gratitude massage as an antidote to stress?
