You are a very nervous fish, fleeing every large ripple . Later, you became used to the ripples but still had no insight into their cause. You can see that a magnificent leap of awareness is required for fish to extend the vision beyond the water in which it is immersed to the source of the ripples.
A similar leap of awareness is required of you. When you understand the source clearly, you'll see that the ripples of your mind have nothing to do with you; you'll watch them, without attachment, no longer compelled to overreact every time a pebble drops. You will be free of the world's turbulence as soon as you calm your thoughts. Remember - when you are troubled, let go of your thoughts and deal with your mind.
