When the Strength card shows up in a tarot card reading, you'll have to contextualize it based on the spread and question you're trying to answer. Essentially, an upright Strength card signifies our own inner strength and willpower to persist, Biddy Tarot notes. Let's say that a passion project you've been working on may not have done as well as you've wanted it to; the Strength card reminds you to keep going and not give in to moments of emotional weariness. The Chariot card has similar themes, but it focuses on outward action and determination. If you draw both the Strength and Chariot cards, the universe really wants you to know what you're doing is going to be rewarded.
If the Strength card appears in reverse, however, it may be time to reflect inwards. Check in on your energy and self-confidence; the card reminds you that your inner strength is still dependable, per Biddy Tarot. According to A Little Spark of Joy, you can apply this advice to relationship problems in a love reading, job rejections in a career reading, as well as health problems.
You're stronger than you may sometimes feel, and this card could be the pep talk you need.
