The midline, an imaginary line which divides the body into symmetrical left and right parts, appears to be the center of the cyclone for spiritual development. In yoga, awakening of midline energy flows (kuṇḍalinī – Indian yoga, tummo – Tibetan yoga) heralds the approach of journey’s end. These advanced flows only stabilize after intense concentration on midline points (chakras – Indian yoga, khor-lo – Tibetan yoga). Practices that aid movement of body energy along the spine and midline help facilitate this effect (kriya or kuṇḍalinī practice – Indian yoga, completion stage practice – Tibetan yoga, inner elixir qigong – Chinese yoga).
If midline meditation represents the fundamental bicycle needed for travel toward journey’s end on the spiritual path, then focus on regions around the midline represents the bike’s training wheels. To illustrate, in Daoism (Chinese yoga), practitioners often concentrate on special off-midline paths in the body known as acupuncture meridians. Outside the nervous system, these meridians act as conduits for electricity, light and other forms of energy. Likewise, in Tibetan yoga (Tibetan Buddhism), practitioners often focus on specific regions of the body and space around it. They visualize intricate patterns extending out many yards from the body in all directions—front, back, to the sides, above and below. For a child, a little extra help at the start of her bike-riding career makes all the difference. The same rings true for midline meditation—nailing one’s intent solely to the midline towers as a nearly impossible task but with the aid of some skillfully selected training wheels a meditator may gradually carpenter enough scaffolding for true midline concentration to take hold.
