so they say the 10 tails is the source of chakra. but they also say that the 10 tails is made entirely of natural energy so in reality its not really made of chakra.

Chakra is the unification of Mental and Physical energies. so a human has chakra because they have both mental and physical energies.

what i theorize is that when Kaguya ate the shinju fruit the natural energy allowed her to mold her Mental and Physical energies together. creating chakra. that was empowered by the vast natural energy of the shinju. when she gave birth to Hagoromo and Hurama. they were born with powerful Chakra. and as such they were powerful. but if it was true that the shinju was the source of chakra(since its made up of natural energy) then that would mean everyone who has chakra would have natural energy bound to them(as in they would all have sage art) its my theory that the fruit of the tree was actually the trees life force. when she ate it she literally became the shinju. she used the vast natural energy to help her mold her mental and physical energies together creating chakra. her body became bound with natural energy and that eventually she evolved into the Gado mazou. from there she turned into the 10 tails form. and that hagoromo and hurama eventually had to seal her away into hagoromo. this would explain how black zetsu was actually the manifestation of her will(since zetsu was created by Madara after he summoned the Gado Mazou and used the life force of the Gado Mazou to replicate the cells of hashirama. it allowed her to force her will onto black zetsu.
