sure TC was definitely happier in denial .. and who wouldnt be? .. right? It would have been way harder to deal .. knowing that he had raped a young girl in reality and not just in an awful dream .. so sure he fought accepting the Land as a reality for as long as he could..
but I think his fight against belief went beyond that .. it was as you say .. to retain his sanity. You are right the Creator which TC engaged in conversation .. told him that he would be revered in the Land if he stayed .. and live out his days in the health and beauty the Land had to offer .. but TC rejected the offer for his sanity's sake.
and to assert his desperate bid of sanity he declared
I told Foul I dont believe in him. I dont believe in you either!
then as quite a contradiction he goes on to say ..
You didnt give me a chance to earn anything. You put me in the Land witout my approval or consent - even without my knowledge. All I did was see the difference between health and disease. Well, its enough for me.
you said ..
If he believed that the land was real, it would be so easy to just stay there
For TC it wouldnt have been
too easy .. and as he proved .. his
need to return to his isolated existence was far his preferred choice than to stay in an idyllic existence where he would be revered from noon till night.
He battled long and hard to endure his life in the face of his leperosy .. his wife leaving him
.. and his return to his own world .. enabled him to regain some semblance of self-respect or some even modicum of his former self ..
.. even after all the injury inflicted on him by public rejection and revulsion and being abandoned by his wife. He went on to return to his writing again
.. and what little achievement it may seem to us .. to his own sense of self-worth .. it spoke volumes! He was entirely different when he returned to the Land in the 2nd chrons.
To TC it would have been
too easy .. and he couldnt accept such a gift that he didnt fully earn .. and his guilt would never allow him to ever believe he would be worthy of such a life.
