When we see a person angry at us, most people will probably react in defense and become angry themselves. Many may wonder why the situation occured to them and blame the other person for having the dust of arrogance (koman). In the Ofudesaki, when any situation occurs, God tells us not to blame others, but to ponder our own minds for these dusts. This angry man appears in our lives by no accident. God tells us that everythng that appears before us is the result of what we have done ourselves before, probably in our previous lives; it is because of the evil thoughts in our own minds that we acted upon them. These evil thoughts are regret, covetousness, self-love and arrogance. They lead to the emotions of anger, hate, and temptations that we often act upon. Whether these sufferings or retributions occur because of God or our own hearts is not important for this explanation now; but these occurences give us the opportunity to purify our minds. If we calm our minds, and ponder our own dusts (in this case arrogance), we can gradually remove this dust from our minds. Yes, initially this angry man may appear to be a negative event in our lives, but this event may actually help us purify our minds, so that our hearts only bring upon joy in the future. Yes, it is our own hearts that bring upon our own fates because we reap what we have sowed. Our actions are dependent on what thoughts are in our minds. This is why the purification of the mind is so important. It is our own hearts that help us do this. Negative fate ibrought upon by our own hearts may not be pleasant; but by its appearance, it gives us an opportunity to bring upon positive fate if we understand what the heart does. This is why in the first verse of the most importanct scripture in the world (Ofudesaki), God tells us we do not understand the heart. To save the world, we must understand the heart! The success of our teachings begin with the understanding of the heart (mune). With the understanding of the heart to purify our minds, all our prayers will be accepted by God.
Also a note: we are no better than these people like this angry man. God tells us that we are on the same path because of the thoughts in our minds. But because we know about the dusts, the heart, and teachings in the Ofudesaki, we have the ability to change our path, to a path that leads to joy. This is why we need to spread the teachings in the Ofudesaki, so that everyone can live the Joyous life.
