I've got to speak up here, too. The forms taught in shaolin do are not like karate kata at all. People on here are talking about these martial arts that they don't seem to have any knowledge of. Are we talking Okinawan karate, or the derived Japanese methods? Naha te, or Shuri te? Or generic American karate/kempo? I can tell you that shaolin do has neither Okinawan nor Japanese material in its curriculum. The closest thing would be the way some of the lower belt techniques are taught as one-step sparring. None of the forms are even close. The most "karate-like" thing are the unforms and belts (which have nothing to do with the material itself).
Another random point...naginata do is not a part of karate do, it is a Japanese koryu/budo. Karate is an Okinawan art that was exported to Japan in the 20th century. Okinawan karate is derived from old styles of Chinese martial arts, including southern shaolin styles. Some Okinawan styles, like Uechi Ryu, are still very close to their Chinese roots.
If you practice a style of karate, and have also practiced shaolin do, and have found matching material please speak up. What style do you practice? What kata does your style have that are also in shaolin do?
