"Knowing what we can do nothing about and accepting it as our destiny, this is supreme virtue." Liou Kia-hway.
I find that when we accept the things we cannot change we create within ourselves a moment of decompression. When we allow ourselves to simply decompress we let go of loads of stress and tension in our bodies. Emotionally we may have a wee bit of a breakdown with lots of tears involved, but this is actually a good thing, as it honours the water element within us. Water is meant to flow, not become stagnant. Thus tears can flow and laughter can ripple.
There are many things in life that we cannot change. We can respond to these things begrudgingly, or we can respond with grace. Which one we respond with demonstrates how much trust we actually have in the Universe, in our particular form of Deity, and most of all in ourselves. We really are forced to let go of our control issues.
All by itself, with no help at all from any of us, the flower will bloom. We can enjoy the process without killing the flower trying to force the blossom open. And once it blooms, the fragrance it gives off is indiscriminately shared with all. This is akin to the compassion we experience for ourselves and others as we let go of control and embrace the grace of acceptance. Compassion is indeed the highest form of love that exists.
