Sit in any comfortable meditation posture. Place the hands on the knees and close the eyes. Relax the body completely. Move your awareness through the body and make sure there is no tension or tightness in any part.
Feel the whole body becoming steady and still. Now become aware of the position of the legs. Feel that the legs are comfortable and the hands are relaxed. Become aware of the hands and arms. Feel that the arms are relaxed and still. Become aware of the whole back. The back is straight but without tension. Bring your awareness to the front of the body. Check that there is no tension in the abdomen or chest. Become aware of the head. There should be no tension between the eyebrows or around the jaw.
Next become aware of the whole body together. Be aware of every part of the body. Feel the stillness of the body. There is no movement in any part of the body. The whole body is comfortable and still. Intensify this awareness of stillness throughout the whole body.
Experience stillness and quietness.
Now open the eyes and gaze intently at the candle flame. Try not to wink or blink. Continue gazing steadily for three minutes. Then close your eyes and try to visualize the after image of the candle flame at the eyebrow centre.
Gaze at the inner image in the same way that you gazed at the external candle flame. Here is a combination of trataka on the external object and the internal after-image. See somewhere in chidakasha a tiny, luminous, coloured dot. Gaze steadily at the dot. It is similar to a small grain of wheat, rice or barley in shape, but the colour changes from moment to moment. The colour depends on how long you have been gazing at the candle flame. After one minute the colour will be black, white or dull brown. After about five minutes, the colour of the dot will be bright red.
If the image is not clear at first, just be aware of whatever you can see. Keep the eye muscles relaxed throughout the practice; this helps you to get a clear inner image. If the image is moving, follow it and gently bring it back to the eyebrow centre. Take a few moments to steady the image. If the image fades or disappears, do not worry; just try to recreate it again. The image will become clear and vivid as the eyes become relaxed and steady.
From moment to moment the dot becomes dimmer and suddenly disappears. All this happens within a few seconds, but you should be careful not to open the eyes.
Even if the psychic point disappears keep your eyes closed. Again try to assemble the psychic awareness and recollect the psychic point. In a few seconds the internal object will reappear, and when it reappears it will have a different colour altogether.
Continue gazing at the internal point with the help of your inner perception, your inner vision, your inner eye. It will grow fainter and fainter and still fainter, and then it will disappear. Do not open your eyes. Assemble your awareness again. Recollect the internal point and see it come once more before your vision.
Thus this psychic point appears, disappears, reappears, disappears, again reappears, becomes dim, disappears, reappears, again grows dimmer and dimmer. Ultimately it becomes absolutely black and merges with the psychic background.
