Chapter thirty-one of the Diamond Sutra inspired me to concern myself with the concept: "We are all made of the same substance.” The great Korean Zen master Seung Sahn Sunim puts it this way:

       "In the big cookie factory we call earth, there are many kinds of cookies. They take many different shapes and have different names, but they are all made from the same dough. Because they are all made from the same material we can make God, we can make Buddha, we can make Demon, we can make Satan. The myriad things in our world all have different names and forms, but the taste is the same. Even people come in many different shapes and colors: western people, Chinese people, Korean people. They all have a different appearance, but their substance is the same. So, the Buddha said, "Above is the dwelling place of all Buddhas, below is the six realms, and all have the same substance. One by one, everything is complete; one by one, everything has it. One by one, everything interpenetrates everything else. One by one, each thing is complete." 

        The thought crossed my mind that even the most disgusting creatures are the same as myself and anything divided by itself equals one. (The Chinese character inside the 1 reads as: “Buddha’s Mind”)

        The title points to the ancient Chinese kong-an: "10,000 Dharmas return to One. Where does the One return?"

[Note: the concept of 10,000 is equal to infinity in ancient Chinese]

        An interesting thing to ponder is what happens when one puts themselves (self) in the denominator and "take the limit" of self while approaching zero?  In other words, when one makes the value of the self "zero"* the result turns the "one" (Buddha's Mind)  into infinity - thus returning infinity to the one.
