The word "Heshang" was derived from the Sanskrit Upādhyāya,(P. Upajjhāya), meaning teacher or mentor. The word was pronounced as Pwājjhaw or Khosha in the regions to the West of China. From there to the Han-inhabited area it was changed into Heshang. Originally it was an honorable title only for those who were capable to be masters, and not to anybody else. This title at first had not been confined to Buddhist monks but might equally be applied to qualified Buddhist nuns. Later on, this word came to be used to address any male who is leading a monastic life. It is not in conformity to the original meaning.
“和尚”原來是從梵文Upādhyāya(P. Upajjhāya)這個字出來的,這個字到了西域被讀成“烏阇”,到了漢地又讀成“和尚”,它的意思就是“師”。和尚本是一個尊稱,要有一定資格堪為人師的才能夠稱和尚,不是任何人都能稱的。這個稱呼并不限于男子,出家女眾有資格的也可以稱和尚。但是后來習俗上這個字被用為對一般出家人的稱呼,而且一般當作是男眾專用的名詞,這是和原來的字義不合的。
