This is a long name but a very simple practice. We’re engaging with the De-reflexive breath technique or what’s known in the spiritual and meditation communities as Krishna’s Kriya Yoga practice.
The invitation is to physically inhale air while mentally exhaling. And likewise, physically exhale and mentally inhale. To help with any confusion, imagine the mental component as light and the physical as air. Then imagine them both passing each other on the same route but going opposite directions. This practice is known to bring neutrality to the whole body system.
I like to think of it as bringing harmony and peace when I’m feeling scattered.
