inner contentment

Influenced by Schopenhauer,
Ancient Greece, Buddhism, Cynicism, and other ancient knowledge,
he sought the formula for happiness.
He realized that life is a painful place.
Because life is a place full of suffering,
he said that the secret to a happy life lies not in achieving pleasure,
but in escaping suffering.
According to him, the only condition for escaping suffering was achieving inner contentment and inner peace.
