I enjoy reading and the outdoors.
Here are some of my finds:
The Breathing App by Eddie Stern, with cue sounds by Moby. Inspired by resonance, the scientific name that describes what happens when our heart rate, heart rate variability, blood pressure, and brainwave function come into a coherent frequency.
A Life Worth Breathing by Max Strom. An easy read, with familiar yogic concepts put into soft language. I read it in one go.
