Actually, as the story goes, Buddha did plan to sit without consideration of food or other worldly comforts/needs to be enlightened. It was thought that serving the flesh robbed you of the spiritual life and thus enlightenment.

It was when, after much suffering and malnutrition, Buddha realized his enlightenment. He realized if he continued he would die and not realize enlightenment. It's when he let go of this idea that he was attached to and take the middle path that he became liberated.

He let go of all of it. No eyes, no ears, no nose...

Cya in the ephemera :)
