A circle is a "ring of light" (a Halo) whose area is π r² and whose circumference is 2πr; where r is the radius of the circle. In Hinduism, the circle is called Mandala; in Christianity, it is the eternal light called glory.

"When the LORD shall build up Zion, he shall appear in his glory" (Psalm 102:16)

Zion: the new Jerusalem 

He: the Father 

Glory: Circle (Halo)

The Father is the Y-Axis of the right angle. This means that the Father is the vertical line drawn from the source (zero) to the top of the circle. Therefore the Father appearing in his glory is represented by a circle and it's radius (r).

Circle = Glory
Radius = Father (Y-Axis)

Consequently, we compute the magnitude of the Father whenever we calculate the radius of the circle. The magnitude of the Father is variable, depending on the size of the radius of the circle.

The magnitude of the Father at an instant is 5cm if the radius of the circle is equal to 5cm. Though the size of the Father may vary, God is constant.

I the Lord do not change. (Malachi 3:6) "NIV"

This means that God is the constant of proportionality in every mathematical calculation. In gravity, he is the gravitational constant (g); in traveling light, he is the speed of light (c). 

Note: the constant of proportionality varies in different media and places because it's true value is nothing (zero). When the force of gravity was created, the gravitational constant which came out of nothing was approximately 10m/s².

In glory (circle) God is pi (π). Pi in glory means double or two. It is the hidden name of God coined into the Hebrew word Yahweh.

Yahweh = π7π`

Where, π = God
7 = Mirror
π` = Image or shadow of God

The image is Jesus, the shadow is Israel. God and his image (Jesus) constitute the tree of life. And God and his shadow (Israel) constitute the tree of the know ledge of good and evil.

The tree of life is π7π`, and the tree of the knowledge of good and evil is ππ`. 7 is the mirror between God (π) and his image (π`). Without the mirror, the relationship between God and his image is ππ`. The absence of 7 implies the removal of the bridge linking man to God.

Note: The shadow is contrary to God because it doesn't reflect the true image of God. ππ` is a disconnect whereby π is God and π` is his shadow. The connection between God and his image was the mirror (7). The removal of the mirror was the separation of God and man. The man isolated from God was Israel.

Israel was the tree of the knowledge of good and evil which doesn't lead to God. Jesus, on the other hand, is the tree of life which leads to God.

π7π` = Tree of Life
          = Non-judgment

ππ` = Tree of Knowledge of Good and Evil
        = Judgement

Since God is π7π`, God is non-judgment. Since the shadow is Israel, π` is Jacob (Israel).

Therefore π7π` is the Axis Mundi where π is heaven (God), π` is earth (Israel), and 7 is the ladder (the bridge) between heaven and earth. This means Israel is transformable to Jesus if he wakes up from his sleep and become a unifying force than a divisive figure.

The Axis Mundi is an object π in front of a mirror (7). Without a mirror, the relationship between God and Israel is ππ`.

Since π (the object) is equal to 22/7, π` (the shadow) is -22/7, God (the object) and Israel (the shadow) are calculated as, ππ` = +22/7 - 22/7
                                                 = 0 (zero)

If you divide π and π` by 22/7, you will discover that God is 1, his shadow is -1, and God and his shadow are equal to nothing (zero). Nothing or void or formless was the state of the universe before the beginning of the world and after the end of the world.

Nothing is the dark circle called Wuji or Ein Sof. The circle is dark to portray that it is hidden. In other words, though the circle is there, it is invisible to the eye because it is hidden in darkness. It becomes a visible "ring of light" when it begins to shine.

The dark circle implies that God is incomprehensible (i.e invisible). Here, man doesn't know God even though God is standing right there with him. Israel (Jacob) was sleeping when God stood with him.

Jacob left Beersheba and set out for Harran. When he reached a certain place, he stopped for the night because the sun had set. Taking one of the stones there, he put it under his head and lay down to sleep. He had a dream in which he saw a stairway resting on the earth, with its top reaching to heaven, and the angels of God were ascending and descending on it. (Genesis 28:10-12) "NIV"

Israel knows God only in dreams, not in reality. The dream world is the shadow. Since Israel is man, man dwells in a dream world (in shadows), not in reality. Because God's promise to Israel is in reality, Israel was unable to receive what God promised while he sleeps. In sleep, God's promise is a strong delusion.

The world must wake up to reality in order to receive what God promised. To wake up is to see the light of this world.

To sleep is to lack understanding. The light is the circle.
