The other methods will deny kundalini, but their denial is not correct they deny it because they are not concerned with it. With the other methods you will have to learn techniques that will help you to feel the corresponding points in the second body or in the third body, and that takes its own time. But with kundalini you can feel each step accurately, and you know where you are. Then your physical body is not concerned you cannot feel anything at all in your physical body. If you work with the fourth, the corresponding points are in the third. If you work with the third body, the corresponding points are in the second body.
