In this passage, the author reflects on the transient nature of relationships and life itself. One may feel sorrow for leaving loved ones, but ultimately, the inevitability of death means that separation will come regardless. The comparison of birds resting on a tree illustrates the temporary bonds we share with one another, highlighting that all encounters are fleeting.
The text suggests that forming a deep sense of ownership over these connections is misguided. It emphasizes that life is filled with impermanence, and clinging too tightly to relationships can lead to disappointment when they inevitably change. Understanding this can help mitigate grief, as the nature of existence involves continual parting and loss.
