[HODOS - Comment by Don Randall]
Greg says that through a "fortuitous error," the Two as One material was put first in his list. An accident? Or the working of Spirit? Two as One is the First Truth of other traditions, expressed as sunyata (Emptiness) in Buddhism, and advaita (nonduality) in Vedanta Hinduism.
The following are some excerpts to illustrate the cross-cultural and timeless truth of Two as One. This truth of ONE must be SEEN/KNOWN/DIRECTLY EXPERIENCED, however, so if one relates to this wisdom only conceptually, it probably remains Two.
Jesus: "that they all may be one, as you, Father, are in me, and I in you; that they also may be one in us, that the world may believe that you have sent me. And the glory which you gave me I have given them, that they may be one just as we are one: I in them, and you in me, that they may be made perfect in one, and that the world may know that you have sent me, and have loved them as you have loved me." John 17:21-23 (JS consensus black)
"The second thing that acts as a hindrance for us is when anything has an opposition within itself. What is meant by opposition? Love and sorrow, white and black--these are in opposition to one another, and opposition has no permanency in BEING." Meister Eckhart in Sermon Four.
"Whatever form your inquiry may take, you must finally come to the one "I," the Self. All these distinctions made between the "I" and "you," Master and disciple, etc., are merely a sign of one's ignorance. The "I" Supreme alone is. To think otherwise is to delude oneself." Ramana Maharshi
"I am this Brahman, One-without-a-second, taintless, immortal Reality, beyond ideas of I and thou, or this and that, the Essence of Infinite Bliss, the Highest Truth." Shankara
"Tao (the Way) has its reality and its signs but is without action or form. You can hand it down but you cannot receive it; you can get it but you cannot see it. It is its own source, its own root. Before Heaven and earth existed it was there, firm from ancient times." Chuang Tzu
"Emptiness [sunyata] is that which stands right in the middle between affirmation and negation, existence and non-existence, eternity and annihilation." Edward Conze
"God's reality must be conceived of on a horizon where there is neither within nor without." Keiji Nishitani
"Good friends, in this teaching of mine, from ancient times up to the present, all have set up no-thought as the main doctrine, non-form as the substance, and non-abiding as the basis. Non-form is to be separated from form even when associated with form. No-thought is not to think even when involved in thought. Non-abiding is the original nature of man." from the Platform Sutra of the Sixth Patriarch
Although different words and concepts are used, I think these samples point to a central teaching of the Perennial Philosophy, i.e., Reality is One, yet manifests in multiplicity. There are many ways of saying this: noumenal reality/phenomenal world, nagual/tonal, heaven/earth, Ground of Being/being, nirvana/samsara, sunyata/form, transcendent/immanent, Absolute/conditional, Brahman/maya, God/ kingdom, One/Two, etc. In the Jesus quote from GJohn, it is easy to see the messianic spin the author gives it, but this does not disguise the essential teaching. "One into Two" appears to be ontological dualism, but it is not, for "Emptiness is Form, Form is Emptiness." Or from Vedanta, "Tat tvam asi!," or "That [Brahman] thou art!" To put it in Christian language, the Kingdom of God is within and among and That is Who we are. This is ontological Truth, even though phenomenologically most of us are in the "sin"/ignorance/blindness of regarding the shadows in the cave to be reality. And of course they are, if we can see through them to recognize Spirit at play.
So for me, the material in Greg's posting is yet more evidence that Jesus was fully awakened to his UNBORN Nature.
