No one is second. Our eyes are foremost in seeing, our ears are foremost in hearing and our nose is foremost in smelling. As soon as one is second, conflicts will arise. So, there is no second. From this, we realize that all existing phenomena in the entire universe are first.
Nothing is second.
Thus, when I visit the leaders of various religions, we often talk about being first. Everything is first. Buddhism, Christianity and Islam are all first. In this way, all of our problems will be solved. When all of our problems are resolved, we can all live together harmoniously.
