Hello. I have a question to Master Kim. Each belt from white to black means assimilation one of the elements as I understand. White - metal, yellow - earth, red - fire, blue - wood, black - water. We saw on a video how assimilation of fire elements gives a power not to burn in fire and assimilation of water element gives a power to stay in water without air for a long time. On the first stage we learn to assimilate metal element. Which opportunities gives the assimilation of metal? Please tell us more about assimilation of all elements.
