Like fishes in the sea, human beings can find, in the air, most of the elements they need to ensure the health of their physical and even psychic bodies. Through breathing they have to learn to get all these elements, which exist in the air in an etheric state.
So here again are some good exercises for you. Know that if you learn to breathe you will not need to resort to so many chemical substances that weigh you down or, in the long run, disrupt your system. Get into the habit of breathing while concentrating on the idea that you are drawing from the atmosphere precious elements, which can nourish and heal you. Yes, your body knows its needs very well: it contains teams of perfectly competent chemists who know how to extract from the air the substances that are most beneficial to you.
