Pleasure or Pain

Meditations - Pg.38 - Marcus Aurelius

Ruling faculty does not disturb itself (Vrttis - in Yoga Philosophy)
 it does not cause itself - pleasure or pain
so no other thing or another person - can disturb you
because
Ruling faculty has the power of forming an opinion
and will not deviate into such a judgment
for it wants nothing
and therefore it is free from pertubration and unimpeded!
