Similarly, you yourself are constantly seeking emotional and psychological homeostasis, whether consciously or unconsciously, and your actions and predilections are generally geared towards inner balance, as well.
The Body's Inner Balance
Inside your body, those aforementioned physiological processes are in motion at all times, and your organs and cells dance in an endless waltz that (generally) results in homeostasis.
For instance, if you begin to get dehydrated, there is a very complicated cascade of hormonal and physiological reactions that attempt to compensate for lack of hydration from outside sources. In very simple terms, your kidneys begin to create less urine, retaining as much fluid in your blood as possible so that your cells have access to the water that's needed for optimal function. Your urine becomes more concentrated (not a bad thing temporarily, but harmful in the long term for many reasons); your eyes contain less fluid; your mouth and mucous membranes become dry; and fluid is pulled away from any organs and tissues that can do with less. Meanwhile, specific receptors in your brain signal the thirst mechanism in an attempt to get you to drink water. It's a delicate balance, and if the dehydration goes too far, you're in trouble.
This is only one very simplified example, and there are numerous other processes, all occurring at the same time, and all in the service of balance and homeostasis.
The Mind's Balance
Just as your body seeks balance, your mind pursues it as well. Countless psychological and emotional processes also work in tandem to help you maintain balance.
Some psychological processes are healthier than others. For example, we can easily compare addiction to the ability to set healthy personal boundaries as demonstrations of how some mental processes are healthier and safer than others.
In your mind, you compensate for your perceived "weaknesses", and you make choices that serve the ultimate goal of balance.
If you grew up in a physically violent household, your mind and psyche will try to maintain inner balance regarding those experiences and memories. You may react in a healthy way, striving to combat that learned violence through self-control, seeking treatment and psychotherapy that serve in your pursuit of a balanced and happy life that's free of violence. On the contrary, your mind may seek balance in an unhealthy way, drowning the memories of violence with alcohol, drugs, and addiction to aberrant behaviors (sex addiction, violence, antisocial tendencies).
Healthy and unhealthy reactions are both enacted in pursuit of balance, but some are obviously more prone to success, happiness, and wellness than others.
Balance is an Inside Job
Whether you're controlling your diet and exercising regularly in order to get your blood sugars under control, or you're in counseling to help you with emotional baggage that gets in the way of your happiness, balance is the key.
Balance is an inside job, and you are constantly pursuing it, consciously or unconsciously, through your choices and habits. Meanwhile, your body also compensates in the interest of balance, and it will go to great physiological lengths to achieve it.
Everything you do has an impact on your psychological, emotional, spiritual, and physical well-being. Strive for balance in all things, and remember that your body and mind will work with you or against you, depending on the quality of your choices and habits. Choose health, choose balance, and choose to make choices and develop habits that serve you in positive and healthful ways.
Balance in all things is the goal we pursue.
