Often the first teacher we come across in infancy and throughout the evolving phases of life, fear is also an expedient teacher. There are some lessons in life best learned as fast as possible. Beyond teaching, our fears can motivate us to change and to grow. If necessity is the mother of invention, then certainly fear is the father. It is also a constant companion of success looming at the boundaries and periphery, reminding us of where we have been and to where we are going.
Fear is a universal wake-up call.
It serves as messenger of our negative ego and it can be the messenger of our more real self. By our Higher Self, by our Soul and Spirit, and by any number of unseen friends. In many ways, it functions like a smoke alarm. We may not like the sound or the interruption, but we recognize it is better to hear the smoke alarm than to be trapped in the fire. I have come to appreciate my fears.
