In this world, each of our minds are different. Each of us have evil thoughts or dusts of disappointment, covetousness, self-love, greed, and arrogance. It is the amount of these dusts we individually have that makes us different. God tells us even between husband and wife, or beween siblings we have different amounts of dusts. No individual is alike. God tells us to remove these dusts.
Why does God want us to remove these evil thoughts in our mind? It is because we tend to act upon them. What happens when we act upon our evil thoughts? Does God punish us? Does it matter? Is there a consequence to our actions? God tells us that our actions, either good or bad creates merits and demerits in our souls, which eventually are released as our fates. We reap what we have sowed.
When our physical body stops functioning, the soul leaves our bodies. It collect our evil thoughts and their associated fates, and continue to our next lives. Our memories are erased, but the two basic elements, the one that make each of us different, and the one that will affect our future, are carried on to the next life. God does not interfere with our thoughts or on their associated fates. We carry them to our next lives.
So it is not God that rewards or punishes us. It is our own souls that monitors our behaviors, and metes out justice. We do not know what fates are around the corner to surprise us in this life time. So what can we do if fate brings upon suffering, or what can we do to prevent our fates from manifesting? We can not go back to the past to change our behavior, but we can ponder our own minds to eliminate any existing evil thoughts that are associated with the present suffering, or future sufferings (fates). How do we do this? It is extremely difficult to just remove the evil thoughts, as these thoughts may be ingrained in the mind. God tells us when fate brings upon suffering, one should ponder their own minds to see what evil thought or thoughts may be associated with the appearance of the present fate. When we do not act upon these thoughts, we can eliminate these evil thoughts from our minds. Sometimes as people have accumulated much dust in their minds, it may take time to eliminate the evil thoughts in the mind. With a pure mind, only positive fates will come from our hearts.
The message is to attain the Original pure mind to live a happy life. But to understand why this occurs, like the information in this post, it is all is in the Ofudesaki, the most sacred scripture in the world.
