He wanted to feed the hunger of his skin. The hunger of his body not so much for orgasm but for that need to be held close and tight, that need we all have to press our nakedness against someone else's.

What indeed tended so greatly to the knowledge of himself, as his appearing in the humiliation of the flesh,—a degradation all the lower indeed if the flesh were only illusory? For it was all the more shameful if he, who brought on himself the Creator’s curse by hanging on a tree, only pretended the assumption of a bodily substance.

He had seen fire, but only when Ara, the lightning, had destroyed some great tree. That any creature of the jungle could produce the red-and-yellow fangs which devoured wood and left nothing but fine dust surprised Tarzan greatly, and why the black warrior had ruined his delicious repast by plunging it into the blighting heat was quite beyond him. Possibly Ara was a friend with whom the Archer was sharing his food.
But, be that as it may, Tarzan would not ruin good meat in any such foolish manner, so he gobbled down a great quantity of the raw flesh, burying the balance of the carcass beside the trail where he could find it upon his return.

Can you really ask what reason Pythagoras had for abstaining from flesh? For my part I rather wonder both by what accident and in what state of soul or mind the first man did so, touched his mouth to gore and brought his lips to the flesh of a dead creature, he who set forth tables of dead, stale bodies and ventured to call food and nourishment the parts that had a little before bellowed and cried, moved and lived. How could his eyes endure the slaughter when throats were slit and hides flayed and limbs torn from limb? How could his nose endure the stench? How was it that the pollution did not turn away his taste, which made contact with the sores of others and sucked juices and serums from mortal wounds? … It is certainly not lions and wolves that we eat out of self-defense; on the contrary, we ignore these and slaughter harmless, tame creatures without stings or teeth to harm us, creatures that, I swear, Nature appears to have produced for the sake of their beauty and grace. But nothing abashed us, not the flower-like tinting of the flesh, not the persuasiveness of the harmonious voice, not the cleanliness of their habits or the unusual intelligence that may be found in the poor wretches. No, for the sake of a little flesh we deprive them of sun, of light, of the duration of life to which they are entitled by birth and being.

He knew that ahead lay many perils—threats to his bodily welfare. And recently Jarles had come to have a great respect for that bag of flesh and bones which contained his ego.

From the body of the loved one's simple, sweetly colored flesh, which our animal instincts urge us to desire, there springs not only the wonder of a new bodily life, but also the enlargement of the horizon of human sympathy and the glow of spiritual understanding which one could never have attained alone.

My flesh was not for feasting on

I saw him going the way of all flesh.

In the darkness, he found her and it was as if the discovery encompassed him at the same time. She was in a secret forest-place of night, where no pain could enter. His body, his lips and hands, made gleams of light by which she could read at last all the answers to hunger. (book 3 chapter 6)

One, two and many: flesh had made him blind, Flesh had one pleasure only in the act, Flesh set one purpose only in the mind — Triumph of flesh and afterwards to find Still those same terrors wherewith flesh was racked.

The wolf howled under the leaves
And spit out the prettiest feathers
Of his meal of fowl:
Like him I consume myself.

What he had yearned to embrace was not the flesh but a down spirit, a spark, the impalpable angel that inhabits the flesh.

[ Hee that makes himself a sheep shall be eat by the wolfe. ]

Your very flesh shall be a great poem...
