I do understand the yin seal, yes you can store chakra in it, but you can also get outdside chakra from it. Ex, Dan and Tsunade, Karin and Tsunade...
Maybe she put Karuma in the seal so that he wouldn't have access to her chakra,and take her chakra as he did with Naruto's. But no body thought about that, did they? The stomach is were the core of all chakra is located,were the power chakra? I think, is located, but instead she stored him in the yin seal, which is on the minds eye chakra, Mito seemed to tame the please so to speak, forcing him to sleep tranquil inside of her. She said that love is what keep keep the beast at bay, so maybe just maybe he was feeding off of her will of love (because he was inside of her seal, which govern the minds chakra, and can be an extension of ones will, instead of her chakra ( like he did with naruto because Kuruma was inside of his stomach).
