This flying seated lotus used to be really hard for me.
Getting into the pose was not the hard part - it was the mind part.
Because my legs are 'bound' if I fall/lose my balance- I most likely would have to use my hands/knees to break my fall and this terrified me.
Practicing this pose regularly and working on the 'mind' part of yoga has helped me become comfortable with flying lotus and even enjoy it.
Warmly, Ren
