It is most likely that the vast majority of BJJ practitioners here and in the real world know about the legend that is Rickson Gracie. A friend of mine shared this with me and I felt compelled to bring it to my steemitBJJ family.
Apparently, Rickson Gracie does not generally allow filming and sharing of his seminars. So this is a rare occurrence full of fantastic technique and philosophy. Prepare your brains for an hour of goodness straight from Komazawa Olympic park gymnasium in Japan.
