There is another instruction on performing this practice, i.e. to visualize five words--Om, Ah, Nu, Da, Ra--in a successive order, in contrast to meditating on one red Ah word alone. This method is quite different. The (Tantra) of the Non-Twofold Victorious Illusoriness says, "Meditating on the four words--Ah, Nu, Da, Ra--in a successive order does not increase more power. It helps little; therefore, this practice may be dispensed with." To meditate on the Om word at the central point is in accord with the saying of Sambhudra and other Tantras[r_nar:85]. However, visualizing a red Ah word is also acceptable. The extremely important point is to meditate on the word at the "central point"; i.e., to meditate on the word in the Throat Center in the Central Channel. Should he be unable to recognize the dream through this visualization, he must practice many, many times. If he still cannot hold the dream, he should visualize a Thig-le [here in the sense of bindu or seed of power] at the point between the eyebrows and hold on to it.

It is difficult to recognize the dream after midnight and before dawn, for this is a period in which sleep is very deep. In the time after daybreak into and through dawn, the

sleep is usually light. During this period it is easy to recognize the dream. Then the yogi should pray to his guru, remind himself of the desire (to hold onto the dream),visualize a white glittering Thig-le at the central point between the eyebrows on his self-Yi-Dam body, and hold onto the visualization. He should also practice the Vase-Breathing exercise seven times; then he will fall asleep again. If he stresses visualizing the glittering Thig-le too much, he will not be able to sleep, or will be prone to awaken easily. In this case, he should visualize the Thig-le as a little darker in hue.
