here
茲 is a rare kanji that points to a location: here. Its standalone meaning is narrow and primarily used in formal or literary contexts.
The exact historical development of 茲 is uncertain. It appears to combine 艹 (grass) with 幺 (thread), but how these components produce the meaning 'here' is unclear.
Picture a patch of grass (艹) with a thread (幺) tied around it, marking this exact spot as 'here'.
For シ, imagine pointing to a spot and saying 'See? Here!' — 'See' cues シ while you point to the marked location.
