Even the great masters of the past trained with other people, researched on their own, and generally did whatever they could to better themselves as martial artists.
A big part of karate is taking the journey as a martial artist yourself. Think of your Sensei as a guide. They can help, but it's you who is going to have to do the leg work. Many martial artists believe that if they show up to class consistently, work hard, and wait long enough a Sensei will teach them everything they know about karate.
This is not true.
Even if it was true, you wouldn't learn the same information as well if you hadn't had the experience of discovering it yourself.
Take the information here and use it as a jumping off point for your own research.
Take what you have found in your research to your Sensei to ask questions, verify validity, etc.
Happy researching!
