Live according to Nature - Marcus Aurelius

The scholar Pierre Hadot answered that living according to nature in the Stoics, meant living according to 3 disciplines:

1. Discipline of action: living benevolently, so that all of mankind flourishes and achieves “happiness”.
2. Discipline of Assent: 
3. Discipline of Desire: self-control over irrational passions, “courage” and endurance in fear and suffering, and “self-discipline” (temperance).
