As the melting snow reveals my garden soil, I think about tilling—working the soil to help seeds grow and produce. Tilling is deep cultivation (6-10” deep). Tilling disturbs and breaks up the settled soil, enables the mixing in of new material, makes planting seeds easier, and helps control weeds. But too much tilling reduces the fertility of the soil. And so it is with my mind. I use my senses, especially reading to break up assumptions, enable new ideas to mix in and grow, and weed out untruths. As with my produce garden, the garden of my mind needs periodic tilling.
