Practices such as Laughter Yoga and the Laughter Wellness method help you feel at peace and good about yourself in the present moment, for no particular reason. They give you the ability to laugh at things that previously would have caused stress or anger, along with the ability to experience a new sense of forgiveness.
There are only 2 things I can do here, now, and they can only happen in the following order. First I must accept everything that I have and love it exactly as it is because it is the only thing that I've got. Then and only if I so wish, I have the opportunity to take action to change it, but that can only happen here, now (not tomorrow or the day after). Laughter Yoga therefore trains me to constantly ask myself: what can I do now, with a positive attitude?
