For the early followers, God through Oyasama taught the early followers how to perform the Joyous Service. To prepare for this Service, God is telling us to purify our minds by understanding what comes from our hearts or mune. Our fates comes from our hearts. When we ponder our fates (sufferings), and not act upon any evil thoughts or dusts in our minds, we can begin to purify our minds. A purified mind is required before God accepts our prayer (Joyous Service).
