More than just a means of connection with the body, this breath offers the gift of assisting you through the barriers of density.
When you begin the Avesa breath, it offers you immediate connection with your present level of consciousness. (See diagram below). As your consciousness is fluid and seeking reunification with your Soul energy, the In-breath opens the doorway to In-soulment, saying yes to your mastery presence.
The Out-breath completes the process through the Avesa alignment. The more you practice the Avesa breath, the simpler the flow from In-breath, (In-soulment), to Out-breath, (Avesa).
What you see in the diagram is the cycle that interrupts this circuit from being completed. It is the density obstacles that present themselves in many forms.
