Breathwork - a very active meditation technique. It's medicine for the body mind and soul.
All we actively are doing is breathing.
Through breathing, into whatever is coming up, old and stagnant energy might release tension and emotions.
There are 3 stages we are living at: Relaxing (during sleep), Doing (daily lives), Running (when something happens).
Imagine, an animal shakes itself after being attacked and something traumatic hapens - so the body is free of the memory created through the situation.
Do we, human beings, do that? No! We keep it in the body and store it somewhere deep down.
