It then become the teacher's job to help you. Being a teacher is demanding and requires love of the art and the desire to keep it going generation to generation. For this your loyalty is deserved. What the teacher gives you stays with you for life. In short, all your chosen teachers deserve your loyalty for they have been loyal to you.
Loyalty is certainly a two way street.
If you want your teacher to favor you, show him or her your loyalty. Before my last Master, Ch'ang Tung Sheng, died, I spoke with him on the phone. I was doing all I could to help him at his last hours. This in fact was being done by all those who were loyal to him. His help came far and wide from his devoted students.
