Since there now is a great deal of literature on the topic of chakras, I will only give a very brief explanation of what they are and where they are located. The human being consists of many different energy levels, both physical and subtle. There are five energy vortexes along the spinal column. They move like wheels and have specific colors. There is an additional vortex in the area of the forehead and one more above the cranium. These are the so-called major chakras (there are also additional, minor chakras). The five chakras situated along the spinal column are associated with the five fingers. The chakras can be compared to transformers, as we know them from the field of electricity. They collect the energy that flows into the body, process and transform it, and distribute it again. The chakras are similar to the intersections of the energy paths, called nadis, which supply them with energy and carry it off again. In addition, they transform the frequencies into sensations that the human being understands: thinking and feeling. They make sure that the lack of energy is compensated for and the diverse energies are in the right place. They can also be called the organs of the energy body.
If consciousness is directed at one of the chakras for a period of time and on a frequent basis, this will activate its energy. This concept shouldn't be taken lightly, since too much energy can also be harmful. If you pay attention to the instructions given here, then only good things can happen. If the body is weakened, the chakras are usually also too weak in their work and a bit more power won't be harmful.
If you would like to learn more about the chakras and how they work, I recommend the following book by Swami Sivananda Radha: Kundalini Yoga for the West: A Foundation for Character Building, Courage and Awareness.20 As you can see in the table on page 206, the chakras and individual fingers also have character traits and talents associated with them.
