three kinds of tranquillity ［三念住・三念処］ ( san-nenjū or san-nenjo): Three aspects of a Buddha’s quality of tranquillity. These are three of the Buddha’s eighteen unshared properties. The first kind of tranquillity is that a Buddha’s mind remains tranquil and undisturbed by feelings of joy when people listen intently to his preaching. The second is that a Buddha’s mind remains peaceful and still, without disappointment, even when people listen unwillingly or are unwilling to listen to his preaching. The third is that a Buddha’s mind remains peaceful and at rest, neither rejoicing nor grieving, when preaching in the presence of these two types of people. Thus a Buddha’s mind remains tranquil regardless of the approval, disapproval, or mixed reactions of those listening to him. See also eighteen unshared properties.
