The garden seems unfamiliar in autumn, because the spring that departed did not have a beloved presence to witness it.

This profound couplet captures the feeling of unexpected loss. The poet says that the garden, now in autumn, feels utterly unfamiliar, estranged. He isn't grieving the passing of the spring itself, but rather the loss of the beloved's presence—the 'Aashna.' It speaks to a deep sense of emotional displacement; the world changes, but the deepest void is left by the absence of a specific, cherished connection.
