pg.68 : meditations: Marcus Aurelius: Book 11
Being Courageous means:
to avoid flattering others!
To avoid being moved by passion and anger!
Such a person who possesses the above:
is made of strength, nerves, and courage!
not the one who is subject to fits of passion and anger and discontent!
Strength is freedom from all passion
Weakness is the sense of pain and anger
and who that yields to pain and anger
both are wounded and both submit!
