Thats a common thing with words - they make one feels knowledgable, performing "'sacred' geometry" excluding everything they can't explain or identify.
Visual art or music as a language address the feeling directly. Perhaps It is okay to get familiar with all the teachings you mentioned, but words more likely will betray when one tries to look beyong the border.
The answer to what it means would depend on what you see. =)
There is quite a bit of symbology here. 'Sacred' geometry, the third eye, lotus position and the aligning of the illuminated chakra points and a serpentine creature looming behind the man.
I suppose it is only natural for an artist to draw what they revere. I would caution people who buy into new age philosophy and modern mysticism. People should become familiar with theology, philosophy and mythology before they decide that this is art or propaganda.
Just a flow of conscience. I doubt I'll be able to decode it in words. I guess it is open for interpretation.=)
It seems like a visit from a 4th dimensional pixel creature. Always a pleasure, Mr. Fool!
