You can become a more relaxed person without all this esoteric bullshit. You obviously dont need it to pick up girls, even though it certainly doesnt hurt and also might help a little bit. When you want to become more relaxed, it is really important to watch your thoughts and not think negatively. A lot of anger and bad thought just comes from the habit of swearing and behaving upset. When you control yourself to not get affected by something bad that happened then you will train your relaxedness and eventually get nerves like steel.
