Among other things, even yoga was teachers who died of cancer.
I'm here too, all the time wondering... if a great teacher has reached such heights in development that they did not make special work to heal itself.... why have they not done??? why they day in and day endured unbearable pain and watched as their body decays???
this is probably another higher level of consciousness... as a person never to understand earthworm
running on the ground assigned to them the mission and realizing that care of the physical body is inevitable they accept suffering with humility and meekness and not fight... did not go against the Universe...
