Though each of us defines "emotional balance" a little differently, all of us must find it. Emotional balance can mean finding and maintaining a positive outlook on life, regardless of what may be happening around us. To some, it might mean an understanding of our emotions that allows us to respond, not react, to our feelings. It can mean that we experience our feelings as intensely as we can while also moderating their excessive expression.
Emotional balance comes with practice in prayer and meditation. We get quiet and share our thoughts and hopes and concerns with the God of our understanding. Then we listen for guidance, awaiting the power to act on that direction.
Eventually, our skills in maintaining near-balance get better, and the wild up-and-down emotional swings we used to experience begin to settle. We develop an ability to let others feel their feelings; we have no need to judge them. And we fully embrace our own personal range of emotions.
