As though lightning just hit his head and he got enlightened, Khal realized something and took a deep breath.
After keeping it inside his lungs for a moment, he opened his mouth and began to blow the air out at a steady, but slow pace.
And to his surprise, just as he did this, the weight on his body began to lessen, while the pain started to vanish slowly!
"It works! I'm a genius! Haha!" laughed Khal wildly, hardly believing his sudden 'idea' had really worked.
He realized what to do the very moment he noticed himself stressed and annoyed over things he usually wouldn't be.
It seemed the key here was the stress. Now that he thought about it, he realized that the weight on his body didn't come because of an invisible power that pushed down on him or because gravity became stronger, but instead because his mind was affected, making him stressed and feel as if his body became heavier and heavier!
