A fully ordained disciple of the Buddha is
called a bhikkhu.
"Mendicant monk" may be suggested as the closest equivalent
for "Bhikkhu", literally it means "he who begs" but bhikkhus
do not beg. They silently stand at the door for alms. They live on what is
spontaneously given by the supporters.
He is not a priest as he is no mediator between God and man.
He has no vows for life, but he is bound by his rules which he takes of his own
accord. He leads a life of voluntary poverty and celibacy. If he is unable to
live the Holy Life, he can discard the robe at any time.
