A couple of things he stresses in the interview
'Brahmacharya, the study of Brahma through related practices'
'The best cave for yoga is a pleasurable family life' ( OK I cringed at this one a little but then the texts do talk about practicing yoga in settled kingdoms, somewhere safe, not in a forest with wild beasts. i guess a pleasurable family life is a 'safe space').
'Real yoga for real people'
'A right yoga for every person'
'Adapt the yoga to the individual not the individual to the yoga'
from Mark Whitwell's website Heart of Yoga
