In yoga breath work which happens there is directly tied into the rest of the practice. it isn’t taught enough in America, but if you find an actual good teacher, of which there do not seem to be many, the benefits are wonderful. Anecdotally and from personal experience, they say that when beginning a consistent practice you will often feel a great euphoria after practicing for 60 or 90 minutes. Can confirm; and it lasts for a couple hours also.

At what level do you experience euphoria? Say on a scale of a low dose of codeine to a standard dose of heroin? Or is it more like the euphoria you get from running? Or the euphoria you get from tripping? Or the euphoria associated with some strains of cannabis? Or the euphoria associated with amphetamines? Or the euphoria associated with ethanol consumption?

Sivananda teaches pranayama as part of their core practice. They are based globally with multiple ashrams in the US.
