These words are good for us who teach to hear and strive for.When he died I felt sorrow, but my heart said "thank you" to my old Sensei. Sometimes we wait for the formal teacher, we imagine it has to be a superhero without defects, and just next to us is the Sensei. Be aware that anyone can teach you, but don't lose the opportunity when you find the one that awakens you. Anyone can use the clothes or look like a professor, but the Sensei is a touch of magic and brings a soft wind of wisdom that you will never forget.
After all if we stay on the path long enough, we all become sensei.
And some need to recognize when they have found one.
