There is yoga in asana but there aint always asana in yoga.
I believe alot of eager students are being misled because they’re visiting teachers that are selling them short by just teaching more or less asana and almost misrepresenting that as all of yoga.It’s a dilution to a balanced practice.There are eight limbs to classical raja yoga, not one. And i believe you can approach them not in any sequence whther you are more of a sitter like a " buddhist meditator or a mover like a hatha yogi.
There maybe partly commercial reasons for this because it feeds into this myth that the body-image is what yoga is all about.This is where propsective students are being mislead and possibly even duped.IWhat is being frequently taught it seems in studios everywhere is it should’nt solely be about placing physical bodies into perfect alignment but finding harmony an all planes of the body/mind matrix through working on them all.You can’t treat one without approaching or treating them all.Alot of teachers seem to be missing this in the way they teach it ,like an over-obsession with what the physcial body is doing.It is almost like a distortion and certainly a watering or dumbing of the inner science.
