Sit in a comfortable position with your spine straight as an arrow. Close your eyes and begin breathing deeply.
Notice which nostril is most open and exhale as if only through that nostril. Imagine a blue-white light flowing in that nostril and reaching the point between your eyebrows. Exhale the same blue-white light out the most open nostril.
Now shift the breath to the other nostril. Imagine a blue-white light as you exhale, focusing on the more closed nostril. Inhale the blue-white light to the point between your eyebrows and out from that point again. Repeat the process until both nostrils are fully open.
Next, focus on breathing in the blue-white light through one nostril, to the point between the eyebrows, and out the other nostril. Then switch on the inhale, breathing in through the one you've just breathed out and exhaling through the other.
Lastly, imagine breathing blue-white light through both nostrils. Relax and allow the light to energize your spirit.
Great quote: Your pain is the breaking of the shell that encloses your understanding.
