“Satya Pratisthayam kriya phalasrayatvam.  To one established in truthfulness, the fruit of one’s actions naturally result according to one’s will.”  -Yoga Sutras II:36

Satya means truth and honesty.  It is one of the yamas, which are these great universal vows that tell us how to interact with the world.  In this sutra, Patanjali, the father of yoga and the man responsible for codifying yoga in the Yoga Sutras, is explaining the benefits of practicing satya/truthfulness.

When we are honest at all times, we mean what we say and say what we mean. There is no separation between the words that come out of our mouths and our actions. And the fruits of our actions reflect this honesty by fulfilling our will.  When you can break down the separation between your words, thoughts and actions by infusing everything you do with honesty, you manifest your will and live the truth. What you say happens. What you think becomes. You manifest and create the life you want.  Start simply… be honest to everyone, including yourself.
