I wanted to say, if u want to know, that all those 4 elements (soul, body, mind, and chakra) need each other to work (couldn't find a better word for "work".. sorry)... that's what I meant... I actually said that before in another comment.. get it?.. I think it's pretty clear that Dan could move, think and act with just his soul. Same goes for Obito. Dan even transferred chakra to Tsunade in his spirit form.

So yea, chakra can exist purely from the soul. It's how Biju work, it's how souls work, it's how Edo Tensei and related jutsu work.
