These bodies consist of the energy of the corresponding universal worlds accordingly, deal with them, and receive the energetic information from them. We call energetic bodies subtle because it is difficult to perceive them with our senses. Nevertheless, we can perceive them when specially trained and used bio-energy methods and techniques. Chakras transform cosmic universal life-support energies into human energy systems. In Sanskrit, the chakra is a wheel of life.
Indian tradition considers invisible chakras as centers of consciousness.
All humans have chakras whether we aware of them or not. Chakras are, in fact, centers of different levels of consciousness, ranging from almost bodily to highly spiritual. Healthy chakras spin all the time bringing energy to the physical body and all its energy layers. Chakras play a very important role in well-being and health. Chakras are an important part of bio-energy systems.
