Strength
Strength explores firmness, patience, and the relationship with impulse. The strength of this card can be expressed through presence and measure, without the need to impose. In Marseille it usually carries XI; in Rider-Waite-Smith, VIII. The numbering does not change its identity within each deck.

What to notice in the image
In Rider-Waite-Smith, a woman and a lion share the center of the scene. The gesture toward the animal invites you to look at how delicacy and intensity relate. The image allows you to explore a way of sustaining tension without confusing strength with a lack of emotions.
Nuances of interpretation
Firmness can protect a boundary; a demand for constant self-control may hide fatigue or tension. Reversed, it can open the question of insecurity or excessive effort, depending on the context. It does not measure courage, personal capacity, or state of health.
An example with other cards
The Tower, Strength, and The Star can gather a shake-up, a patient response, and an opening to hope. The second card does not eliminate the impact of the first: it changes the way of accompanying it. Thus, the set contains more nuances than an isolated reading of difficulty.
