"For the ego, aloneness is never a joy. Ego enjoys only when it subordinates somebody, when it can say, 'I am higher than you, bigger than you.'
"Ego can never enjoy aloneness in aloneness what is the point of having an ego?"
Osho pg. 115 "Golden Nuggets"
That's why there is so much corruption in the Martial Arts, because Martial Art classes are taught in groups, within groups, there is a lot of ego embellishment that has nothing to do with Martial Arts and is a distraction towards spiritual growth. In personal training, this is not present, there is no one to compare to in personal training, it is about your own development.
