If Rebirth is not taken literally then why seek Enlightenment? I've read that some Buddhists do not believe in the literality of rebirth. As someone who is new to the study of Buddhism, this is confusing to me. My understanding, which perhaps is incorrect, is that a Buddhist seeks enlightenment in order to obtain emancipation from Samsara. Yet Samsara is a cycle of rebirth, thus if rebirth is not taken literally it seems natural to then not take Samsara literally. If this is so, then what kind of emancipation is sought after in seeking enlightenment? Isn't the goal of seeking enlightenment to eliminate rebirth? What then are other reasons for seeking enlightenment apart from the emancipation from Samsara?
I am a Rinzai Zen Monk with a decade-long monastic background so my answer will be relevant within our school's framework.

From a Zen POV being 'reborn' exists only within Reality.
Reality is purely this one moment here and now.
With each breath, with each action we are reborn. The choices we make are fresh and new. The Enlightened being will make those choices in accordance with what they experience.
Because they are living in the here and now they are also making these choices without any reference to the past or the future because these are purely abstract concepts since neither of them is here and now.

The Enlightened person is literally reborn with each and every experience (in Japanese Zen terms these are known as 'Nen' - ie. the time it takes to register each experience). An Enlightenment experience is when you fully experience this for the first time: when a drop of water falling on your head or the call of a crow suddenly awaken you to this new awareness

There are other types of rebirth of course. Such as the delusional rebirths, when one succumbs to any of the poisons (Ignorance, Anger, Greed) and is reborn in 'hell'.

Buddhism is a very wide philosophy with a wide application of the same basic terms and concepts. What i have just said is not really valid for a Theravada Buddhist. It would be explained, understood and practiced differently by someone of a Pure land Path (JoDo ShinShu for instance) even though they are part of the Mahayana.
