urge, force, imminent, spur on
迫 centers on pressure that pushes something forward or makes it urgent: urging, forcing, or an imminent approach. The idea of spurring on fits as a forceful push toward action.
迫 combines 辶 (movement) with 白, which likely contributes the sound and suggests pressing or approaching. The exact historical role of 白 is uncertain.
The movement radical 辶 wraps around 白 (white). Imagine a white-hot urgency moving closer and closer, forcing you to act.
