When describing a state of equilibrium or harmony, the term "in balance" is often used. However, there are several other synonyms that convey a similar meaning. For instance, "stable" suggests feelings or situations that are secure and reliable. "Equilibrium" means that all forces are balanced and equal, and "harmonious" suggests a pleasing arrangement of elements that work together seamlessly. "Symmetrical" refers to balance achieved through a uniform and proportional design. Meanwhile, "proportionate" suggests that all parts or factors are correctly weighted or sized in relation to one another. Additionally, "even" conveys a sense of consistency and balance, while "centered" suggests being well-grounded and focused.
