From Apollonius I Learned Freedom Of Will

No Longer Let Thy Breathing Only Act In Concert With The Air Which Surrounds Thee, But Let Thy Intelligence Also Now Be In Harmony With The Intelligence Which Embraces All Things. For The Intelligent Power Is No Less Diffused In All Parts And Pervades All Things For Him Who Is Willing To Draw It To Him Than The Aërial Power For Him Who Is Able To Respire It.

To A Rational Being It Is The Same Thing To Act According To Nature And According To Reason.

Your Mind Will Be Like Its Habitual Thoughts; For The Soul Becomes Dyed With The Color Of Its Thoughts. Soak It Then In Such Trains Of Thoughts As, For Example: Where Life Is Possible At All, A Right Life Is Possible.

Everywhere And At All Times It Is In Thy Power Piously To Acquiesce In Thy Present Condition, And To Behave Justly To Those Who Are About Thee, And To Exert Thy Skill Upon Thy Present Thoughts, That Nothing Shall Steal Into Them Without Being Well Examined.

Ambition Means Tying Your Well-being To What Other People Say Or Do. Self-indulgence Means Tying It To The Things That Happen To You. Sanity Means Tying It To Your Own Actions.
