Summary
This quote suggests that once a rebellion has begun, there is no turning back or hiding from its consequences. It implies that once people rise up against an oppressive authority or injustice, they must fully commit to their cause and accept the potential risks and hardships that come with it. The idea is that once the "sword of rebellion" is drawn, there is no need to hold onto the "sheath" of caution or restraint, as it becomes irrelevant and unnecessary in the face of a fight for freedom or change.
