We fear certain classes and students. We may even fear coming to work. Often, we carry fear from our personal and home life into the classroom. It might be useful to quickly jot down all the fears that pass through our mind. We can distinguish between a concern and a fear through the moment to moment awareness of our spiritual state of affairs.
Most people are unaware of the present condition of their mind.
The mind is a useful tool but a poor master. Spiritual is defined as our ever present mental well being or lack thereof. In contrast, concerns are valid flags prompting possible action. Fear, often accompanied by adrenaline rushes, physical tension or rigidity, is the ego's attempt to place itself into a superior safe place. The ego always protects itself, acting in self-defense.
