The primordial spiral is the manifested world, while Akasha is the unmanifested, or emptiness itself. All of reality is an interplay between these two things; Yang and Yin, or consciousness and matter. The spiral has often been represented by the snake, the downward current, while the bird or blooming lotus flower has represented the upward current or transcendence. The ancient traditions taught that a human being can become a bridge extending from the outer to the inner, from gross to subtle, from the lower chakras to the higher chakras. To balance the inner and the outer is what the Buddha called the middle way, or what Aristotle called the Golden Mean. You can be that bridge.
