In this Sahā world it is difficult to eliminate earthly desires completely. Even so, we learn from our mistakes while we are living in the Sahā World full of suffering. We merge into the Original Buddha’s life, become involved in the Buddha’s life and live in the Buddha’s life. Thus, both good and evil deeds are reflected upon and can help us not to create these mistakes again. This is called Kai-ye, which re-evaluates things from the point of view of the Buddha’s enlightenment, gets them involved in the world of the Lotus Sūtra and finds the value of the things. As a result, everything is unified with the Lotus Sūtra and becomes an object of appreciation and respect.
