Think of spiritual illness as a sauce. A bit too much of one spice and the sauce becomes unpalatable. Too much of all the spices and the sauce becomes overtaken.
When spiritual illness is brewing, the balance of decisions and actions is important. Too many wasteful and waste-producing activities tip the balance towards illness. Activities that revive the sense of connection tip the balance towards fine.
Spiritual health, like the spices of a dish, is one component of health. The other components: physical health, emotional health, and intellectual health are the more obvious aspects of health, but without the spicing the meal stays unimaginative. The spicing causes the meal to ignite the appetite, interest the taste buds, and involve the memory. So too with spiritual health.
A sense of spiritual connection ignites the imagination. A sense of spiritual guidance interests the thoughts. A sense of spiritual longing passes from generation to generation. The seasoning of the life is rich and satisfying.
Spiritual illness can occur “when spiritual questioning causes imbalance that the body cannot fathom.” (see https://energy-guidance-complete.com/2015/06/24/spiritual-illness-strikes/) Spiritual pondering is a normal part of spiritual health, but when pondering becomes denying or when viewpoint is viewed as supreme, spiritual illness takes hold. The spicing becomes cloying or too intense, and the struggle to continue is magnified.
Seasoning is done through trial and error and through following those who tried before. Seasoning can be the best aspects of a dish or the worst. Spiritual health can raise up the life and spiritual illness can sink the life. Finding balance is necessary for fulfilling and joyous living.
