“A great way to understand this is to think of each Chakra like a light bulb, the job of a light bulb is to distribute light to the area around it, the light or energy is supplied by a large energy station, if the light bulb is working well, the right amount of light energy will be distributed, if the light bulb malfunctions, it may distribute too much light or not enough, causing problems.”
