Twilight Despair 5 wrote: How I explain chakra is this. Chakra is formed by combining the two forces physical and spiritual/mental energy. However before Hagoromo gave people chakra, they couldn't combined them together. The chakra of the God Tree allows one to combine the two forces together. That is why Kaguya believe all chakra was her's on Earth. As she gained that chakra first to combined her energies. Her sons inherited some from their mother. Same with their children, and finally he split chakra to the rest of Earth. So even though people techically generate the energy to make chakra. Fragments of Kaguya's chakra to combine the energy inherit in all things were then fragmented and confined. Theory.

That's actually pretty good theory you got there.
