The above is interesting but I believe that the subtleties are lost until we reach a very high degree of spiritual advancement.
The guna qualities are probably more immediately applicable to most individuals, no matter what the advancement level.
I get your point about the gunas. But I also have found that the general vibrational frequencies we let affect our aura of food, environmental stimulation, reading and people in our life add much to the spiritual experiences and general uplifting and draining affects on our consciousness. In the meantime (until we our in higher ages or raise our own consciousness) we constantly need to stop look and listen to those who have more sensitivity on such matters.
