Shape Transformation
Shape Transformation(形態変化, Keitai Henka) is an advanced form of chakra control and a technique that is pivotal for the manipulating of chakra and the creation of new jutsu. It involves changing the shape and movement of chakra, determining the size, range, and purpose of a jutsu.
The ultimate example of shape manipulation is the Rasengan, which is described as shape manipulation that has been taken "to the highest possible level." The Rasengan relies heavily on chakra control and does not require the use of Hand Seals. By building up on precepts learned from the Tree Climbing Practice and Water Surface Walking Practice chakra control exercises, the Rasengan is chakra that has been rotated and then compressed into the shape of a sphere.
