Psychology = Gemini is a virtue & principle of logical thinking, communicating in your surroundings. This energy makes you get into the kind of conversation/Thinking (Mercury) where you get into many scenarios through multiple angles (Mutable Air). Therefore, you know that your spirit is
using the masculine side of mercury (Sacral chakra) when you use this energy. On the other hand (Mercury) can make you nervous and experience stomach butterflies if you overuse it. Also, breathing naturally or forcefully affects our thoughts and feelings. That is why Gemini represents the respiratory system. You can practice many different breathing patterns to experience an altered mind state using oxygen (Mercury). Furthermore, when air is expelled from the lungs, it raises the trachea and runs into constriction at the larynx where the vocal cords (Taurus/Neck), now called vocal folds, cause vocal folds to vibrate or buzz. This buzzing quality to the speech is called voice or voicing; the vocal folds “chop” the air streams into a series of “rapid puff” that create sounds consonants B, C, D, F, G, J, K, L, M, N, etc. that’s why breath control is essential in rapping and singing, Acting.
Physiology = The main functions of the respiratory system are to obtain oxygen from the external environment and supply it to the cells and remove from the body the carbon dioxide produced by cellular metabolism. Always remember for every physical issue there is a psychological aspect.
