Chakra is the concept in Hinduism and Buddhism that there are various focal points in your body where energy is concentrated. The word comes from Sanskrit cakra, which meant "wheel", because it was implied that chakra was a "wheel of dharma" or "wheel of time" in various sources. Through Proto-Indo-Iranian, cakra further derives from the Proto-Indo-European root keklos, which could mean "wheel" or "circle". Keklos also became the Ancient Greek word kyklos, which became Latin cyclus, which became cycle; and the Proto-Germanic word hwewlaz, which became Old English hweol, which became Modern English wheel. It's pretty crazy that those words, which all seem so different, are connected by only several millenia of change, which isn't that much on a larger time scale of things.
