The couplet questions whether the streams of love's river overflowed during high tide, attributing this surge of emotion to the arrival of an evening hour.

This beautiful couplet paints a picture of overwhelming emotion. It asks, "Have the streams of the river of love overflowed like a high tide?" This is a poetic way of saying that feelings of love have surged intensely, just as the ocean swells during high tide. The poet then addresses their own heart, remarking, "Oh mind, such an evening time has arrived." This suggests that these powerful emotions have come upon them specifically in the quiet, reflective hours of the evening. It's a moment of deep introspection, where love's current feels irresistibly strong, filling the heart completely as dusk settles in.
