I've taken that to mean that all chakra is generated from there.
Well, what Kishi calls 'chakra' is called 'qi', 'ki', or 'chi' in real life (depending on which language you're transliterating). The chakras are places where ki collects and does stuff. Kind of like Kishi's chakra gates. Presumably, Kishi didn't use 'ki' because Toriyama already did (like how Hunter x Hunter uses 'nen' for the same basic idea).

I bet the chakra article on Wikipedia will make a lot more sense to you now.
