The flowing, fast-moving water of a river is far less likely to contain impurities than trapped water that pools in swamps and hollows. Standing water is an incubator for bacteria, is often contaminated, unsafe to drink, a breeding ground of mosquitoes.
When feelings are allowed to flow through the body, they too are safe; they do not poison or destroy the container that conveys it. But when our emotional life is blocked, put off by distractions and the busyness of life, it becomes toxic; pressure builds over time, it seeks out other routes; the blocked energy eventually floods, spreading all that has developed in this damaging state.
And so when we open to our feelings as they arise, we create the causes and conditions of mental and physical health. This is what acceptance-based inner awareness entails; it is not a practice to put off, any more than breathing, sleeping, or consuming nourishment.
