Answer:
The misery of being away from God after having known the joys of Heaven.
Step-by-step explanation:
Christopher Marlowe's "The Tragical History of the Life and Death of Doctor Faustus" revolves around the character of Dr. Faustus, a well known German scholar. Dissatisfied with the traditional knowledge that the world provides, he embarks on a deal with the devil, thus acquiring ways to know the wisdom beyond human capacity.
Mephistophilis was the servant of the Devil who helps Faustus and partakes in the deal and convincing him about the deal. He also facilitates whatever requests Faustus has, acting as an agent for the devil. When asked by Faustus how hell feels like, he remarks that hell is the misery of being away from God after knowing the joys of Heaven. He also added that Hell is everywhere and it is the dam ned who are forever cut away from God and his kingdom.
