One of the best ways is to go to nature and feel the calm of a lake or the serenity of a meadow, filled with wild flowers and the chirping of birds. Looking into the bright eyes of a squirrel or a puppy will also bring the wonder that goes with deep feelings of peace. You will see all the order of the universe around you and realize it is all put together very well.
Grass is not struggling to grow, flowers are not putting forth their blooms with great effort. All of nature operates with effortless ease. Tap into that and you will feel the natural peace that is your birthright.
