Does the will to live cease after enlightenment? What would motivate an enlightened person to continue living? It seems like once somebody attains enlightenment, other than teaching, there would be no reason to continue living.
"Ceasing the will to live" sounds depressingly suicidal. That's not a good description.

Dhammapada 203-204 describes Nirvana as the highest bliss.

You could say that the craving to enjoy life and, the craving to do or become something in life ceases.

When you look at your remaining years of life, and think that "in the next years or decades, I can travel to many countries, spend more time with my family, enjoy different types of food, build a career, become successful, raise my children to be successful etc." - well, that kind of thinking and emotions cease after enlightenment and is replaced with the peaceful bliss of the moment.
