No blessings from the master. Ive worked with some high level masters and they have never mentioned anything about blessings from a master not to say that doesnt happen. What i have understood is that those masters who were selective in the past did not have their art survive because they could never “find” a person in who to part the teachings. Now a days or at least since the 70’s the saying is “Many talk, few do.” Took me ten years to get 1 black belt in ninjitsu and mastery is ten black belts and there are ten mastery levels. I have seen plenty of people come and go. Mastery five is avoiding a live blade attack from behind and 10 is catching an arrow being shot from a japanese bow with both hands straight on. Takes a lot of spiritual training that our societies dont offer us time to engage in so you get it where you can. I hope you find the time in your own life to develop the spirit. We will surely need it in the coming times and at the end of life. We are all burdened with desires. Even the desire to have no desire is still a desire so have the desire to be of service in that we will always be working on the spirit and removing obstacles infront of others.
