Alan Watts video question re life as spectrum

[zenpop]

Last night I was listening to a playlist of Alan Watts talks on Soundcloud and in one of them he talked about life being akin to a spectrum, like the way light moves through a prism, and although there are all the different colors revealed it is the same light, etc.

When I tried to locate the sound file (or a video) of that particular talk and theme, I could not find it. It's maddening because I really wanted to study the inquiry he'd brought forth again -- given I was in a half-sleep state when I heard it last night.

Is there any chance anyone here knows which file I'm referencing and where I might find it?

Thanks much,

ZP
