Impermanence
This is from a book I am currently reading and I would like to share it with you all:
Fear and anxiety are the dominant psychological states of the human mind. Behind the fear lies a constant longing to be certain. We are afraid of the unknown. The mind's craving for confirmation is rooted in our fear of impermanence.
Fearlessness is generated when you can appreciate uncertainty, when you have faith in the impossibility of these interconnected components remaining static and permanent. You will find yourself, in a very true sense, preparing for the worst while allowing for the best. You become dignified and majestic. By knowing that something is lying in wait for you just around the bend, by accepting that countless potentialities exist from this moment forward, you acquire the skill of pervasive awareness and foresight like that of a gifted general, not paranoid but prepared.
