Mastery

No person teaches you mastery, the thing your mastering teaches you mastery.
In swimming, the coach doesn't teach you, the water teaches you.
In tai chi, the master doesn't teach you, the stance teaches you.
In meditation, the book or the guru doesn't teach you, the practice teaches you.
In art, the instructor doesn't teach you, the medium teaches you.

Pray, Meditate, Practice, Mature.

Be still.  Listen to the thing that you're mastering.  What is it teaching you at this moment.
