Eventually, Gilgamesh reaches the garden of the gods and meets the goddess Siduri, who advises him to accept mortality and appreciate the life he has. Gilgamesh takes her advice and returns to Uruk, where he shares his wisdom and experiences with the people.
Thus, the denouement of the poem involves the resolution of Gilgamesh's quest and his acceptance of mortality, leading to a sense of closure and reconciliation with the natural order of life and death.
