Defining 'the earth is rhyming'

the introduction to this concept

In the depth, when you found an end,
In the ground, when you found what she send,
In the rime, when you got hot chocolate,
In the time, when you met your mate.
The feeling that you have at that moment,
When you scream, "Eureka", for what you were trying to invent,
This feeling, it is the tithe a tiny part of what we call: 'the earth is rhyming'.
