Babayada,
I love Pink Floyd, and there is no doubt that it puts one in a psychedelic type of mind frame. Just like there are certain songs, which when they come on the radio, cause a 100 degree change of my mood or mind state, from being blah, to totally upbeat (maybe a little bit of the Pavlovian principle working here too).
But do these audio streams put one in the so called "awakened mind state"? - the mind state which can be physically measured, recorded, and compared using instruments such as the EEG or MRI?
Not that this state or the physical sensations one may feel when being in that state are necessarily going to be superior or more euphoric than listening to Pink Floyd or one of the other songs. All it would indicate is that one's brain wave pattern is similiar to that noticed in experienced, long term meditators. Maybe the reason that these people dedicate so much of their time, and put them selves through so much (rigor?) to reach that state is beneficial in some way? - I would hope so!
In fact Paul Scheele in one of his seminars remarks that his feeling is that the state of enlightenment may actually be quite boring, because everything will be so calm and peaceful! Or maybe not, maybe one will feel things much more intensely than normal, but be able to handle them? Who knows!!!
