From the half-closed doors, I saw his chest, yards wide and overflowing with blood.

This couplet paints a powerful image: someone is secretly peeking through half-closed doors. From this hidden vantage point, they observe a figure with a remarkably broad and strong chest. This chest is described as 'gaj gaj wide,' emphasizing its immense size, and is perhaps splattered with blood, suggesting a recent intense struggle, a wound, or profound passion. It's a moment of intimate, concealed observation, capturing a raw and impactful scene of strength and potential vulnerability from a distance. The observer might feel awe, concern, or a sense of intrigue.
