look intently
矚 centers on fixing one's gaze with deep concentration: looking intently at something, as if studying or scrutinizing it closely.
矚 combines 目 (eye) with 屬, which likely contributes the sound and may suggest connection or focus, together expressing intent looking.
The eye 目 is fixed on the complex, many-part shape 屬, like someone staring intently at a detailed object to understand every part.
For ショク, imagine a person looking so intently that their gaze feels like a shock: shock -> ショク, and the eye 目 is locked onto the target.
