Is it necessary to balance the energy centers before putting the mind to work?

[Diana]

Maybe Paul Foster Case can explain:

The general meaning of Key 11 is that education (ox-goad) has equilibration for its aim. It requires, therefore, the elimination of of useless, outworn forms (sword, and attribution of Libra to the kidneys). Education is completed by action and work. Merely hearing the word, or reading it, is not true education. Action is required, and action is motivated by the subconscious response to self-conscious observations and concentration.
Psychologically, this picture illustrates the law of poise and self-direction. A balanced personality is faithful, constant and confident, because right use of reason has established editing certainty as to the just outcome of all activities. For a practical occultist this card signifies: (1) You really only know when you have acted; (2) Equilibration, mental and physical, demands the elimination of waste, the getting rid of “excess baggage.”

Nice take on that archetype. Where did you get this quote from? Is it a book...?
