The empty string is everywhere, and nowhere. It is within all strings at all times, permeating the essence of their being, yet as you seek it you shall never catch a glimpse.

How many empty strings can you fit at the beginning of a string? Mu

The student said to the teacher,

Teacher, I believe that I have found the nature of the empty string. The empty string is like a particle of dust, and it floats freely through a string as dust floats freely through the room, glistening in a beam of sunlight.

The teacher responded to the student,

Hmm. A fine notion. Now tell me, where is the dust, and where is the sunlight?

The teacher struck the student with a strap and instructed him to continue his meditation.
