佛說五無返復經 1.11

1.11

He also spoke to the dead man's wife: "Your husband is already dead; why do you not weep?" The wife also spoke a parable for the brahmacārin, saying, "We husband and wife came together through causes and conditions for only a brief moment. It is like flying birds that roost together on a tall tree in the evening to spend the night, and rising early toward dawn, each flies away on its own to seek food. When there is affinity, they gather; when the affinity ends, they separate. We husband and wife are just like this: his departing or staying, advancing or stopping, is not within my power. When the retribution of impermanence arrives, each follows their own destiny; we cannot save one another."
