Our body is much more than what our eyes tell us. One way of explaining it, is the parallel to hearing. Humans have a limited range of what wavelengths we can hear. Then there are other animals that hear sounds of higher or lower wavelengths than we do. There are so many sounds surrounding us, that we are unaware of. Same with our vision. So many wavelengths that our eyes don't perceive. One of the things that are there even though we can not see them, are our chakras.
The chakras support our body with energy. Chakras, meaning 'wheel' in Sanskrit language, spin. This movement is rather the intensity of the chakra's strength. The stronger this intensity, the brighter and stronger the chakra. Chakras together support the energy flow. But they also have their own specific body parts and organs as well as non-physical aspects to maintain with life. Non-physical aspects being for example emotions and perception/understanding/consciousness.
The human form (not only in human species but in several extraterrestrial ones as well) has great potential of awareness. It is a fact that humans only use a small percentage of their brains, and we don't seem to be able to use the other parts of it. This relates to all the potentials we have that are awaiting our discovery. Things such as telepathy, immortality, breatharianism, and many other things, are available. But we know that people in general have not reached these things. We also see that many people are unable to experience unconditional love towards others and themselves, or even lacking the ability of being in touch with their emotions, intuition or thoughts. This relates to the fact that most people do not have all chakras active.
