Please have read about Regulating the Breath. If you experiment only with the 'in-smell' you will get dizzy and heaven knows what. You must first learn to regulate your breathing. I take no responsibility for anyone stupid!
The In-SmellThe first areas for sensing smell are the nose and the nostrils.
When i smell something strong, or something bad, i recognise it straight away and sense it very clearly in my nose, often at the tip of the nose. This seems logical, it's a wake up signal, either to contract the nostrils, filter out the bad smell and not inhale; or to savour and take this scent in, to ingest it.
The nostrils and smelling are very similar to the eyelids and seeing. But humans hardly ever use their nostrils. We need to do a few stretching exercises. We need a little nostril yoga ... Smells are sensed initially in the nostrils. Perhaps you've noticed how the stink of a bad perfume, hangs around in your nostrils for long minutes after the experience ...
The nostrils adjust to temperature and smells. Unless you live in a hot land, the in-breath is cooler than the out-breath. Cool and dry air is warmed and moistened by it's passage through the nasal canals. The nostrils may even contract a little, to warm or moisten the air on the in-breath.
When smelling-in with a general curiosity for scents on the wind, the nostrils expand. But if you flare your nostrils and just breathe-in, rather than smelling-in, the cool dry air will give you a sore throat. Thus it seems obvious that dogs who flare their nostrils when sleeping, are smelling-in.
We can do all sorts of funny things with the nostrils to channel smells, to refine and clarify them and search out the scents. Long forgotten and never used muscles become fully obvious once we start scenting. We sometimes contract the upper nostril while flaring the lower, and sometimes the outer rims narrow and almost seem to hold the smell at the top of the nose ... it's all very interesting, but i have no analysis of it all. Discover it for yourself ...
When dogs smell in a focused way, they contract the nostrils with short sniffs. Some people do this when they smell something specific, like perfume or wine.
Experiment with something which smells nice, a cut lemon under the nose, ... enjoy the smell, ... read on ...
After the nostrils, scents pass through the nasal canals. I doubt if any animal or child would realise that they have nasal canals. What it feels like, for humans who are so out of practice, is that the breath and smell seem to curl round into the back and sides of the mouth, and (if your tongue is relaxed and hanging), on the upper surface of the tongue and the roof of the mouth. The impression it gives us is that the roof of the mouth feels much higher than it actually is.
Experiment with freshly cut onion, and afterwards by smelling soy sauce.
Then experiment with freshly cut onion a few feet away on one side and soy sauce on the other, try to smell both by 'smelling in their direction'. I feel sure animals know the direction of a smell, and that they can smell in two different directions at the same time. I feel sure i can do this.
Smell is an ever changing experience out of doors. Since practicing with scenting i have become a lot more aware of petrol smells. I find this unpleasant, but i breathe them in anyway, if i'm aware of them at least i have a choice to move, or not to inhale deeply.
Indoors, where there is no wind, in your own room, most of your in-smell will be a mixture of your own body scent, and your own out breath. This may be reassuring, but it is not stimulating.The First Smelling Exercises discuss aroma therapy oils and household equivalents.
This is just a start, there must hundreds of ways of waking up our sense of smell. It needs to be developed creatively over a period of time, with an awareness of the different smells in your everyday life. Please experiment and give me feedback.
