I have to say I haven't a clue what you are on about, but I don't care, I love the piece. I have no idea what Sentakusha might be, but if it refers to Time and the illusion of it's passage, then I am right there with you. The past is as malleable as the future and the present is the Real of it all.

Wonderful shading and dream like light that pulls me into the paintings subconscious.
