The concept of reincarnation and causality is difficult to comprehend for many people. Many of the philosophers in the past have believed in these concepts. If one is prone to believe that the universe operates in a rational and scientific process, these concepts will be easy to understand.
In the Osashizu, the following verse from God:
If I say “causality,” you probably do not understand it. The entire world is a mirror. Although all human beings go through births and rebirths, each way you used your mind is accurately reflected to your body. Understand this well. February 15, 1888
The mirror reflects our image back to our eyes, as our actions or thoughts reflect back to us in the future. But the effects of our actions are not immediate like the image reflected to our eyes from the mirror. This is why many have a difficulty comprehending causality. There is no immediate relationship seen.
Understand that what occurs to us daily is the result of our own actions, and indirectly out of God’s guidance. We can then stop blaming others for our problems, and begin to truly work on improving our future. This is done my removing evil (greed, arrogance, and self love) from our hearts. Like the mirror that reflects a true image, what occurs to us daily, is a means to gauge our spiritual maturity. If we ponder our circumstances, and remove evil from our hearts, the mirror will only reflect joy.
