Mudra – A position of the body which is symbolic of a certain attitude or activity, such as teaching or protecting. Although mudra technically refers to the whole body and the body does not have to be that of the Buddha, in common usage this term most often refers to the hand positions chosen for statues of the Buddha. Each hand position is symbolic of a certain characteristic such as supreme wisdom or serenity.

Nirvana – Literally: cessation or extinction. Although nirvana is the ultimate goal of many Buddhists it should never be confused with the Western notion of heaven. Instead, nirvana simply means an end to samsara.

Samu – Work Practice. A very plain gi is often worn for this, This is work, usually physical, done in a mindful and aware manner. Tasks should be carried out in silence, though speaking in hushed tones is permitted when clarification or further instructions are needed. Simply stated, samu is a form of meditation done while working.

To form this position, first one hand should gently be made into a loose fist with the thumb held inside.

One of the best known is the Heart Sutra. A short sutra is often called a gatha.

Another distinctive chracteristic of zen is that the person of the Buddha is regarded with somewhat less reverence than in most other Buddhist traditions.

Zendo – Zen room or hall. This is the main room, whether it be in a monastery, retreat center or residential home, where zazen and other zen practices are observed.
