Breathing and its workings have been studied closely by yogis in India for many thousands of years and they have understood their importance for our vitality and also for the correct functioning of our mind.

So, in order to make contact with certain entities or regions in the spiritual world, we need to find its specific rhythm and use it as we would a key.

The same goes for breathing: in order to make contact with a specific region in the universe, we must know which rhythm to use
