In Balinese ancient texts (lontars), pra means first; prana, power nala, inner fire; and pranala, circulation. The word Prana comes from two roots, Pra means first, and na is the unit of energy by extension spirit. Therefore, prana can be understood as first unity of (energy) spirit.
At first, we learn to move awareness in the frontal passage or “frontal nadi”, and then we explore the energy in the spine, spinal channelor “sushumna nadi”. When the spine is flexible and healthy, and devoid of blockages, the inner balance can take place.
The breathing is an essential part of a Yoga Pranala practice. The breath initiates and finishes the movement. When we are consciously breathing we are channeling prana/spirit/ conciousness. The breath is the vehicle that carries spirit within, through and around our body. At first, we use our awareness to lead the energy but eventually it is the energy that leads us.
