當位

Denotes structural correspondence between an entity's inherent quality (nature or rank) and its placement within a system. In cosmological or divinatory contexts, it specifically indicates that the internal quality of an element is congruent with its external position, signaling stability, legitimacy, or a lack of structural friction.

May function as a predicate ("is in the proper position"), an attributive modifier, or a conditional statement.

Distinguished from //zhèng wèi// (正位), which refers to objective orthodoxy; 當位 emphasizes the active correspondence between the occupant and the requirements of the position. It describes structural alignment rather than individual moral merit.

Avoid overly literal translations such as "occupying a seat," which may obscure the term's systemic weight. The term implies propriety in the sense of cosmic or structural fitness. When encountered in passages involving conflict, determine if 當位 is presented as an existing advantage (structural support) or a missing requirement (lack of legitimacy).
