The Master said,"At fifteen I set my heart upon learning.At thirty,Iplanted my feet upon the ground.At forty,I no longer suffered from perplexities.At fifty,I knew what were the biddings of heaven.At sixty,I heard them with docile ear.At seventy,I could follow the dictates of my own heart;for what I desired no longer overstepped the boundaries of right."
