Like most great spiritual truths, gratitude is stunningly simple. This is not to say it's necessarily easy to practice. All kinds of distractions, obfuscation, and negative attitudes from our upbringings may get in the way. But all you really have to do to receive gratitude's gift is to make a commitment to be thankful on a daily basis, and the world will be suddenly transformed into a beautiful wonderland in which you are invited to play.
