Thanks for sharing the video. Wise words from Puppetji!
Subtle is the key word, I think its seemingly complex, but in actuality its so simple that it's almost impossible to see. In other words, seeing what is is really not difficult or complex, what's complex is the dropping of all the conditioned thoughts preventing the seeing. I think the most difficult part is the discipline required to quiet the monkey mind in order to allow the "seeing" or awareness to happen.
