What do I have to do to learn it?

Well, basically, you apply an oil to your exposed skin and then remain completely still. The oil makes you passively absorb nature energy, so then it's a matter of learning to shape it and combine it with your chakra. If you start getting too much, I can knock the energy out of you, but in order to get enough to really learn anything you'll have to learn to draw in more than the oil will provide.
