It rushes towards the eternal reality day and night. It cannot be bound by transient worldly ties.

This couplet beautifully illustrates how an eternal, unchangeable truth or reality is perpetually sought after. We constantly strive for it, day and night. However, it's a profound essence that simply cannot be contained or bound by any temporary, worldly ties, fleeting desires, or our attempts to control it. It reminds us that the ultimate truth transcends all our human constructs and remains ever free and unbound, despite our continuous pursuit.
