We learn to touch the ground of being by unlearning our neurotic tendency to identify with impermanent, external phenomena.
Our state of mind is changing from one moment to the next. With the thought of something attractive we become excited. When we encounter something undesirable we become resistant. Regardless of whether the thought is pleasant or unpleasant our state of mind is affected. States of mind are like weather conditions, they are constantly in a state of fluctuation. This instability gives rise to a sense of paranoia. We feel like we have to monitor the environment for changing conditions. So, we invest a great deal of time and energy trying to avoid unpleasant situations, and seeking out more desirable ones.
