As a Sagittarian, you are naturally drawn to philosophical thinking. You may even have spent your time seeking the truth for yourself and your place in the world, and you're not afraid to go off the beaten path. This is why balance is essential.
Temperance represents your longing pursuit for purpose. This card, as it relates to yourself as a Sagittarian, is guiding you to be mindful of your ideas and how your role in people's lives affect others. There must be a balance between your need for independence and your commitment to other people in your life.
If you plan on going on grand adventures, make sure you are not doing it to excess. You will need to find balance within your desires and passions to keep long term relationships if you desire to have them. As a Sagittarian, it is easy for you to be honest with others about how you feel, but you may need to learn to balance your words and actions with others who aren't as confident as you are. Not everyone seeks the world as you do, and not everyone has the same sense of adventure and independence. Learning and practicing patience is what Temperance is offering you.
The secret about patience is that the need for patience is all about boundaries and respect. When the Universe is asking you for patience, the request is about having you learn how to honor other people's boundaries, and boundaries include people's feelings, emotions, and abilities to learn at their own pace. In the end, when seeking truth, don't just seek your own. Ask yourself what lies true for others, and then you will learn real balance.
