The adverbial forms, such as paścimena, can mean "towards
the west" or "in the west"
. In texts like the Manusmṛti, Mahābhārata, and various
Upanishads, references to paścima denote positioning
relative to the cardinal directions, e.g., temple entrances
facing the west (paścima-dvāra) or celestial orientations.
The root adjective paścima (पश्चिम) is widely used in classical
Sanskrit to denote the west or western direction
Paścima can function as:
Temporal or Spatial Connotation
Beyond literal direction, paścāt and related forms carry a figurative
sense of "after," "behind," or "subsequent," connecting spatial
orientation with sequences in time or hierarchy
For example, in philosophical or ritual contexts, it can signify
the "last," "hindmost," or "ultimate" position, such as the last
rites or final stage in a sequence.
Etymology
Derived from the root paśca meaning "behind," "posterior," or "last."
The addition of suffixes transforms it into adjectives or adverbs
that express western orientation (paścima, paścimena) or temporal
declension (paścāt)
