“And therefore if the head and the body are to be well, you must begin by curing the soul; that is the first and essential thing. And the care of the soul, my dear youth, has to be effected by the use of certain charms, and these charms are fair words; and by them temperance is implanted in the soul, and where temperance comes and stays, there health is speedily imparted, not only to the head, but to the whole body.” by Socrates – as captured by Plato in “Charmides”
"Whenever a man tries in life to get his own way in some matter, this is an expression of his egoism. Whenever he wants to force on others something he thinks right and loses his temper over it, that is an expression of his self-seeking. This self-seeking must be subdued before he can attain to truth. Truth is something we experience in our most inward being — and yet it liberates us increasingly from ourselves. Of course, it is essential that nothing save the love of truth should enter into our striving for it. If passions, instincts and desires, from which the Sentient Soul must be cleansed before the Intellectual Soul can strive for truth, come into it, they will prevent a man from getting away from himself and will keep his Ego tied to a fixed viewpoint. In the search for truth, the only passion that must not be discarded is love." [Rudolf Steiner]

"Temperance, in the days when the Tarot was invented meant tempering or modifying. It therefore suggests adaptation. (Here note that the digit value of XIV is V, and 5 means adaptation.) Adaptation is the basis of all practical work in Hermetic science. The Emerald Tablet says, “As all things are from One, so all have their birth from this One Thing by adaptation.” Hermetic scientists endeavor to imitate nature, and adaptation is their method. To adapt is to equalize, to adjust, to coordinate, and to equilibrate. Therefore it is written, “Equilibrium is the basis of the Great Work.” [Paul Foster Case - Learning Tarot Essentials, c. 1932]
A.E. Waite
"A winged angel, with the sign of the sun upon his forehead and on his breast the square and triangle of the septenary. I speak of him in the masculine sense, but the figure is neither male nor female. It is held to be pouring the essences of life from chalice to chalice. It has one foot upon the earth and one upon waters, thus illustrating the nature of the essences.
A direct path goes up to certain heights on the verge of the horizon, and above there is a great light, through which a crown is seen vaguely. Hereof is some part of the Secret of Eternal Life, as it is possible to man in his incarnation. All the conventional emblems are renounced herein.
So also are the conventional meanings, which refer to changes in the seasons, perpetual movement of life and even the combination of ideas. It is, moreover, untrue to say that the figure symbolizes the genius of the sun, though it is the analogy of solar light, realized in the third part of our human triplicity. It is called Temperance fantastically, because, when the rule of it obtains in our consciousness, it tempers, combines and harmonises the psychic and material natures. Under that rule we know in our rational part something of whence we came and whither we are going." [The Pictorial Key to the Tarot, by A.E. Waite, c. 1911]
