Board Thread:Theories and Speculation/@comment-26061639-20150131220909

I was trying to figure out how hashirama learned to use senjutsu, and this is what I think

since Hashirama used wood release being able to grow trees, flowers and so on, we can say he was very closed to nature and therefore the first thing that came to my mind was that he used wood to continuesly recollect natural energy and then send it to him (sending chakra's possible, in fact Nagato used to send chakra to his 6 corps who had metal bars to recieve it). this theory would explain why as long as I remember Hashirama's sage mode was not time limited.

then I remembered that jubi used natural energy and as jubi used wood release I think this fact supports my theory.

my theory doesn't explain how he learned to control natural energy and enter into sage mode so I guess either somebody thaught him or he found some kind of scroll which thaught him those secrets so what do you guys think about it???
