Today I’m drinking a glass of water that tastes much better than the one I had yesterday. Not that I noticed anything wrong with yesterday’s water, but I did notice that it was time to change the filter I use. The difference is dramatic, the taste softer on the tongue—something like cashmere vs. leather.

The water filter works beautifully when it’s fresh. It removes minerals and chemicals, yielding the clear, sweet essence of water. It accomplishes this by absorbing the unwanted elements, but after a time it simply cannot take in any more. The filter’s loss of function is subtle, incremental, and at first it’s hardly noticeable. But eventually the filter stops working, and will actually introduce impurities into the water if it isn’t changed. The water tastes bad.

All of which has me thinking about the psyche’s filters.

Messages, images, and information are everywhere, more than we can ever process. The needs, demands, requests, and unthinking effects of other people’s actions continually challenge our ability to respond. We cannot let everything in; there’s too much. But determining how to filter our experience requires effort.

When the air is thick with frustration and anger, callousness and mindlessness, that’s what we most easily absorb. Without a conscious effort to resist them, negative mindsets permeate our way of being. It’s important to see the world around us as clearly as possible, but to live compassionately requires being careful of what we allow to become part of us.

Yet even when we are mindful about the ways we sort and learn from our experience, eventually the filter becomes too saturated to do its work. The anxiety we encounter begins to color our own emotional life. Thoughts become infused with the taint of fear or resentment in the air around us. It’s time to change the filter.

The upper portion of my Brita pitcher is designed to hold the cylindrical filter securely and allow it to be changed easily. I just lift the lid and drop the new one in. Sometimes I wish I could do that with my mind, but our filters are more complex. It’s through spiritual practice that they become clean again.

The hardest part about cleaning or changing a water filter is remembering to do it. That may be the case with our psyche’s filters as well. The means of restoring spiritual strength and resiliency are as different as people are varied. But we all need our spiritual health to live fully and well. We need the ability to cleanse our thoughts, perceptions, emotions, and motivations. We need a way to experience the pure, sweet essence of life that will nurture and sustain us.

Cleaning the filter might happen through prayer or meditation. It might mean a walk in the woods, yoga, or an exercise routine. It can occur in the experience of music or poetry. It could result from our own means of artistic expression. It may grow out of our relationships or from doing our best work.

Spiritual practice restores us and enhances our ability to take in what we need for health and wholeness. In whatever way we find effective, it’s important to keep up with those practices that cleanse the filter. It changes our way of being in the world, and that changes the world.
