Video, words, voice and music are all by Brenda Clews, who notes in the YouTube description:

I meditate regularly and often do yoga sets. Especially I do this when I am working through issues. During one of my sessions last week the metaphor of the wall arose, and while resting after the yoga set I picked up my iPhone and began speaking, intending to write a prose poem from my voice notes. I left the recording as is, and added the background of sounds and instruments. My speaking of the words is not a performance but an embodiment of the meaning. Then I began to work with recent footage of a lightning storm I had shot. Initially, when looking at the rushes, I was perturbed that I hadn’t removed the mesh screen. Yet the footage is perfect for this video. The subconscious is all of a processing, mobile, energy of constantly equilibrating unity, and what we are voicing here is what we are filming there. Our lives are always moving beyond their boundaries as we push into deeper processes of who we are, alone and together.

Brenda also blogged a few process notes at Rubies in Crystal, where she went into more detail about the soundtrack:

The sound track is a midi file of the text that I generated at http://www.p22.com/musicfont/ and yes, I used copters, and gunshot, and a pad4choir from the music text generator (I did have to copy the sound files from the site one by one and mix them later) and ethereal sunrise, smooth clav, whirly, and nature sounds from GarageBand, plus the original track of thunder and lightning, so it is meant to be a bit, well a bit of a war zone. It works, but it’s not for relaxation, obviously!
