All of the main orifices or apertures of the body are incisions designed to connect us to the material world. They are conduits or link points for the spirit/soul, allowing it to savor or experience the diversity and richness of matter. The most basic or numerous apertures are the tiny pores on your skin which breathe and mantain the body's intergrity. In the regenerated or breatharian state it is in fact possible to breathe soley through one's skin pores.

Breathing is an involuntary function designed to bring oxygen to the lungs and circulatory system refreshing the entire body, but it also to serves expel or burn fine waste or matter which would otherwise accumulate and/or poison us. All orifices expel waste of some kind.

Smell is particular to the nose, and gives us a sense of pleasure or disgust according to the fragrances emitted by an object or person. Odor, smell, or, fragrance is in fact a very fine form of airborne food emitted from the host and literally eaten or absorbed by the recipient. It is the purest and most nutritious part of the host or food and is free for us to enjoy. When we cook our food we kill it forcing the life force out of it which is the sweet or pleasant odor you smell around you. All life force has a sweetness or purity to it. By cooking and eating the host or food we cross the line and commit murder or kill.

The first humans neither ate nor drank and when they did eat it was mostly fruits or berries and was done for pleasure rather than need. Many were simply satisfied by the fragrance or smell. There existed whole tribes and nations that existed this way for thousands of years, but their history has been lost or suppressed. One such tribe is the Astomi of India whom Pliny the Elder write about...

The Astomoi(Astomi) or Mouthless Ones

Pliny the Elder, author, philosopher, and military commander of the 1st century AD, in his Natural History, writes about THE ASTOMOI (or Astomi) who were an Indian tribe of hair-covered men without mouths, who obtained their only nourishment from the scent of aromatic plants and fruits. Other than his report, not much imformation is available on this strange race. Pliny writes....
"At the extreme boundary of India to the East, near the source of the Ganges, he [the Greek historian Megasthenes C4th BC] puts the Astomi tribe, that has no mouth and a body hairy all over; they dress in cottonwool and live only on the air they breath and the scent they inhale through their nostrils; they have no food or drink except the different odours of the roots and flowers and wild apples, which they carry with them on their longer journeys so as not to lack a supply of scent; he says they can easily be killed by a rather stronger odour than usual." - Pliny, Natural History 7.26 source
Another source(Sir John Mandeville) tells "There is another isle that men call Pitan, men of this land till no land, for they eat nought, and they are small, but not so small as Pygmys. These men live with smell of wilde apples, and when they go far out of the countr, they bear apples with them, for anon, as they lose the savor of apples they dye." source
