Interpretation
The modern interpretation of the card stresses discipline and control. The lion represents the primal or id-like part of the mind, and the woman, the 'higher' or more elevated parts of the mind. The card tells the Querent to be wary of base emotions and impulse. For example, in The Chariot card, the Querant is fighting a battle. The difference is that in Strength, the battle is mainly internal rather than external.
In the Crowley deck this card is entitled Lust, and receives a different focus, as a sun sign (zodiac), namely Leo, implying a potency that is sexual, creative, and intuitive, which are all attributes of the element Fire. The other Leonine quality of generosity, or mercy, is also an aspect of this power or strength. There is a further connection with the heart chakra in kundalini yoga.
If inverted, the Querant is in danger of losing control to impulses and desires. Pride and unwarranted anger are also often associated with the inverted card.
Some refer to it simply as a challenging situation requiring persistence and effort.
