Is samana the same as digestion?

It governs digestion and is not identical with it. The wind is the movement of gathering; agni is the fire that transforms what has been gathered.

In the classical accounts, eating without appetite, eating in distraction, and taking in more impressions than can be processed.

What it does

Samana is the wind of processing. Prana brings food, air and impression in; apana takes waste out; samana is what happens between the two. In Ayurveda it works directly with agni, the digestive fire, and the pair is treated as the hinge of physical health.

The same word, sam, gives us balance and equality. The gathering it names is not hoarding but bringing things level.

The metabolic reading

The extension to experience is old rather than modern. What is true of food is taken to be true of everything: a day, an argument, a piece of news all have to be broken down and assimilated, and doing that badly leaves residue.

That is why unprocessed experience shows up in this system as a navel problem rather than a head one.

Working with it

Kapalabhati and agni sara act directly here, both on an empty stomach and both easy to overdo. The quieter practice is to eat one meal without a screen, at a table, slowly, which sounds like advice from a different discipline and is exactly what samana practice amounts to.
