Mechanism of the Person Blowing Thread From His Mouth

The mechanism of the person blowing thread out of his mouth.

Within the lines of thread pouring out of his mouth,
another self, smaller in size, appears,
which is also blowing out fine lines of thread in a smaller fashion.
The lines of thread exhaled are inhaled, and then exhaled again.
Each time, the lines become different things.

Repeating this process, the lines become thinner and thinner
until finally they evaporate into the air.
