The Bön Mother Tantra, among other tantric texts, explains that the mind rides on the vital breath/energy currents like a rider on a horse, and the two travel together through the pathways of the channels. As the breath circulating in the channels becomes more balanced, the channels become increasingly pliable, allowing the vital breath currents to find their own comfortably smooth rhythm.
We visualise the breath moving through our channels has the same attributes of emptiness like the sun shining in the sky. All positive qualities arise from the base of this channel, clearing and removing suffering and misery with the help of the breath. When the channels are clear, wisdom – selwa – can arise.
