I once asked a Tenrikyo minister, if we had the gift (sazuke), why do we not go to hospitals to heal everyone. Would this not be the way to spread our religion to the world? I do not remember his answer, as I just wanted to get my point across. But today I believe that my question was not appropriate for the following reasons:
Oyasama did not send Kokan to heal people in the city. She went out to propagate the teachings of God. So my question to you is, are we following Oyasama’s path when we go out to heal people we do not know? I can be wrong, but people came to Oyasama to be healed, instead of her going out to heal people. In the Christian religion, Jesus and the disciples went out to heal people. Why does it make a difference if they come to us or if we go out to heal them? It is my opinion that God wants us to spread the teachings before we ask God to heal anyone. God wants faith through reasoning instead of blind faith by performing miracles of healing. By informing people first, we give them faith through reasoning. We are teaching them a path to a joyous life. What would be the purpose of God healing someone if they do not understand why suffering or joy exist in this life or understand that there is a path of joy.
In the Ofudesaki, God tells us that people will come from the high mountains to be saved. God tells us that we must spread the truth of the heart, and tell people what guidance to expect to understand the heart. After we have spread the truth to people, with our special prayer performed with a sincere mind, it is God that brings these people to our places of worship to be healed of the guidance given. These people come to us to be healed. In summary, we yobokus go out to spread the truth to others like what Kokan did; but they come to us to healed. We heal them and continue to remind them of the heart and God’s teachings. This is the way we save the world. Again, I feel like we are putting the cart before the horse. We need to purify our minds, and spread God’s truth, before our prayers are accepted by God. This includes our daily prayer (Joyous Service) and the sazuke.
