“Lama” is a Tibetan word, with the same meaning as “Heshang”. This word was misused too since it, in its original sense, was not applicable to everyone leading a monastic life. properly speaking, the tile for those who have revived ten precepts is Samanera, while for those who have been given the higher ordination it is Bhikkhu; in the same way, the tile for female acceptors of ten precpts is Samaneri and for the female acceptors of the higher ordination it is Bhikkhuni.
