To get your spiritual practices right, you need to learn how to breathe accordingly:
In Qigong, we inhale through the nose and exhale through the mouth, holding our tongue up the palate, leading our breath to fill our stomach. This is where our center is located, called Dantien.
In Yoga, we both inhale and exhale through our nose, making a noise with our throat chakra. You can also do something called “fire breathing” where one rolls the stomach.
Either way is used in Meditation, where your focus should be on your breath, to feel more present, letting thoughts come and go. Finding peace.
Our breath is also what symbolises spirit, where the element of air, can be seen as both the carrier, and a metaphor, for spirit. In Hawaii, this is acknowledged through the greeting “Aloha”, which means that we affirm sharing breath, sharing life.
