Just as the colors of the rainbow
Unite to make one light
God far above and God deep within,
YHVH and Shechinah,
Unite in Shabbat.
Transcendence unites with Immanence,
One and One becoming One.

We join together in community
Together reflecting God's splendor.
We are the colors of the rainbow
Uniting to make one light.
The glorious holy throne
Is here where we meet
Ready for Shabbat to rest upon us.

HaMakom, this sacred Place, uplifts us
Here where electrons dance
And the interplay of Being and Nothingness
Draws our hearts together, binary code
Flickering through space
Making us present to each other
And to the radiance of Shabbat.

We crown Her from below
And She enfolds us in new supernal souls
So that our service
Be blissful and praiseful,
Joyful and radiant
As with shining faces
We approach the Bar'chu --

The prayer known as K'Gavna comes from the Zohar, and describes the mystical joining of transcendence (God-far-above, the Kadosh Baruch Hu) with immanence (God-deep-within, Shechinah) as Shabbat arrives. It speaks in the language of the seven "lower sefirot" (emanations or aspects of qualities of God) which are sometimes mapped to the seven colors of the rainbow. (That rainbow imagery for divinity is especially lovely now during June. Happy Pride Month everyone!)

In some siddurim K'Gavna is a prelude to the Bar'chu, the formal Call to Prayer that comes between Kabbalat Shabbat and the evening service. This variation was written for the 2020 Clear Vision Reb Zalman Legacy Shabbaton that R' David Markus and I co-led over the weekend over Zoom for Havurh Shir Hadash in Ashland OR. It dovetails with that Shabbaton's themes of sacred space, digital presence, and what it means to come together in community online.

On a related note, here's my d'var from the weekend: Being Real, Digital Edition. And here's R' David's d'var from the weekend: The Mishkan's Next Digital (R)Evolution.
