Appendix C to Chapters 6 and 7
The main difference between my meditation now and a year ago, is that whole body breathing is now whole body smelling. And when indoors i use the aroma oils.
BACK TO THE WIND
I don't know if it checks out in animal behaviour, but sounds and smells are carried by the wind, so when outside, it makes sense to sit or stand with your back to the wind. Infront you can use your eyes. - Then listening and smelling anew with each change of wind.
I don't know much about phrenomes ... but phrenomes are transported, (they communicate with their recipient) through the breathing, and this is an added importance of smelling.
Sensing Inside the Body is the next step in Dozing
It seems that Buddhism refers to an internal awareness of smelling, tasting, listening and seeing, but there is probably much debate on the meanings of these passages, (ref) and i have never heard of any Buddhist practicing this.
Listen to the sounds inside your body (especially while scenting).
Listening activates the awareness in a special specific way - listening seeing and tasting all activate the awareness in special specific ways - they bring out facets of the awareness which we don't use with our brain guided awareness.
In the same way you can listen out in a specific direction, you can listen in to your body, to specific muscles and joints, they don't often make noises, but just being open to the possibility, opens up our awareness. Listen out with exactly the same attitude as listening out to the world outside
This is not a mystical way of sensing, it is possibly based on a form of imagination .. but then i'm guessig animals also have this form of imaginary sensing, and these unused aspects of our imagination and awareness can be very useful in practice.
