A Buddhist monk is a "bhikkhu" in Pali, Sanskrit "bhikṣu", while a nun is a "bhikkhuni", Sanskrit "bhikṣuṇī". These words literally mean "beggar" or "one who lives by alms", and it was traditional in early Buddhism for the Sangha to go on "alms round" for food, walking or standing quietly in populated areas with alms bowls ready to receive food offerings each day. Although in the vinaya laid down by the Gautama Buddha, the Sangha was not allowed to engage directly in agriculture, this later changed in some Mahayana schools when Buddhism moved to East Asia, so that in the East Asian cultural sphere, the monastic community traditionally has engaged in agriculture. An emphasis on working for food is attributed to additional training guidelines laid down by a Chan Buddhist master, Baizhang Huaihai, notably the phrase, "A day without work is a day without food" ().
