The eighteen characteristics of a fully realized being not shared by ordinary beings, namely that he never stumbles, never raises his voice, never loses mindfulness, and so forth.

See “eighteen unique qualities of a buddha.”

Eighteen special features of a buddha’s physical state, realization, activity, and wisdom that are not shared by ordinary beings.

These are eighteen unique qualities possessed by a buddha. They are “unique” in the sense that they are only possessed by buddhas and not by any other type of being. There are slight variations in the wording and order of the eighteen items found among various sources. For three canonical works that list the eighteen, see The Perfection of Wisdom in Ten Thousand Lines (Toh 11) at 2.8, The Jewel Cloud (Toh 231) at 1.249, and Distinctly Ascertaining the Meanings (Toh 317) at 1.96.

This refers to eighteen properties/qualities that are unique to buddhas, “property” being one of the possible meanings of the term dharma.

See “eighteen distinct attributes of a buddha.”

See “eighteen distinct qualities of the buddhas.”

The detailed list of the eighteen qualities is found in UT22084-026-001-5834.

The list of eighteen unshared qualities in the Ananta­mukhapariśo­dhana­nirdeśa varies slightly from other canonical lists. Elsewhere, the first quality is that the buddhas are “consistent in their actions.” The list in the Ananta­mukhapariśo­dhana­nirdeśa also includes an additional member at position thirteen: “their liberated wisdom vision never wanes.” The eighteen are generally given as: (1) their actions are consistent; (2) their speech is not jarring; (3) they are not forgetful; (4) their state of cessation is not a state of indifference; (5) their perception is not discursive; (6) their minds are always composed; (7) their diligence never wanes; (8) their recollection never wanes; (9) their effort never wanes; (10) their meditative absorption never wanes; (11) their insight never wanes; (12) their liberation never wanes; (13) their physical actions are guided by wisdom and are in alignment with wisdom; (14) their verbal actions are guided by wisdom and are in alignment with wisdom; (15) their mental actions are guided by wisdom and are in alignment with wisdom; (16) their wisdom vision is unobstructed and unaffected by the past; (17) their wisdom vision is unobstructed and unaffected by the future; and (18) their wisdom vision is unobstructed and unaffected by the present.
