Loss of spiritual energy.

"I turned back and walked toward him, looking hard

into his burning eyes. Instinctively, distrustfully, he

flinched. Still, when I grabbed his right hand and turned

his palm up, he didn’t push me away. I inspected the

lines and found them deep, cracked, marking uneven

paths. Bit by bit, the colors in his aura appeared to me:

a rusty brown and a blue so pale as to be almost gray.

His spiritual energy was hollowed out and thinned

around the edges, as if it had no more strength to

defend itself against the outside world. Deep inside, the

Man was no more alive  than a wilting plant. To make up

for the loss of his spiritual  energy, he had doubled up his physical energy, which he used in excess."
