There are two images below. Fill your screen with one of them (hiding this text).

Stare at the image as long as you can keep your eyes open then close your eyes and look for the after image of the flame through the darkness. Keeping your eyes closed, hold the after image as long as you are able. Practice holding the image longer each time you do it. This forces you to concentrate on seeing the image and you will pay less attention to your normal stream of consciousness and one day you will suddenly realize you have found the place of Silence wthin your Self. The first stage of Enlightenment. Do not expect this to happen the first time or by the the tenth time or the hundredth time (although it may). You won't be able to force it or will it, it will come to you when you are ready... not when you think you're ready. Know that even once mastered, it is but a first step in a process that will grow, change and evolve within you over time. Eventually you will not need an outside image but will see your image the moment you close your eyes and take a deep breath. Beyond that you will bypass your image and go directly into a higher level of consciousness where you are able to connect with your Higher Self, your Soul. Over time... over a long time, perhaps over many lifetimes, you will be able to easily maintain direct contact with your soul and beyond.
