This meditative sitting is best done facing north or east. The performances of a few rounds of deep and conscious breathing in Shavasana prior to this meditative sitting can serve to enhance its effect drastically. Sit in Vajrasana or take up any sitting posture in which you are absolutely certain that the spine is yogically erect. This makes sure that the energy can move upwards in an effortless and smooth manner. Perform the chakra pranayama as follows. While breathing in, visualize pranic energy rising from the base of your spine up through the six chakras situated along the cerebral spinal axis. While you breathe out, visualize the prana coming out through the same six chakras. Imagine that your body is a six-storied building and the prana is rising and descending on an elevator. A held in and held out breath can be added appropriately at the back of the brow's center, the Agya Chakra, and at the base of the spine, the mooladhara chakra. As you come up through the chakras, starting from the base of the spine, and through to beyond the top of your head, try to become aware of each of these centers. With practice and inner brow, these centers start to become conscious centers filling with light, sound and color. When the breath is completely filled in, and you are in the Sahasrara Chakra, beyond the top of your head, hold your breath in a prana kumbhaka, a held in breath for a lengthy period of time. Slowly, let the breath out and keep your concentration in the thousand petal lotus chakra. Let the breath take on any form it wishes and simply hold the idea that you are sitting in the midst of a beautiful thousand petaled pink lotus. Hold that idea as long as you can repeating the visualization over and over until a pleasing sensation of being suspended comes about.
