Now that you have that down we can move on to the next part of your chakra control training. You need to understand how the concept of the leaf being held to your forehead works at a higher level. Holding the leaf to your forehead only requires a small amount of chakra. This next training exercise will teach you how to control large levels of chakra. In this training, you will be channeling your chakra to the bottom of your feet. After you channel what you feel to be the proper amount of chakra, run toward a tree at full speed. Once you get close to a tree, place one foot on the tree. Use the chakra on the sole of that foot to grab onto the bark of the tree. Then life your other foot and place it above the first foot. Use this foot to grab onto the bark of the tree as well. By using your chakra to hold onto the tree, try to run vertically straight up it. This is similar to the first exercise, but it is more advanced in that you have to focus chakra to both of your feet and evenly through the soles of your feet, and you will have to hold the weight of your entire body. If the chakra is not even on the soles you will simply fall off. On top of that, even if the chakra is even, if the chakra is too weak you won't be able to grab onto the grab and if it is too strong you will be pushed off the tree as it causes the bark to break under too much pressure.
