There’s a ‘brain’ in my gut? Someone say it ain’t so.
If it’s true then it means that what goes on down there
Is of its own intelligence and has control
Of my thoughts and emotions. Yet it has no soul.
I thought I was the smart one. Now I must beware
Of the microprocessor that resides below.

It can’t generate thought but affects those of mine
In a way that science is beginning to see.
But for eons before now the yogis have known
Of this brain in the fuel tank. In fact, it’s been shown
That the vagus nerve, when stimulated, can be
Good for one’s mood adjustment by nature’s design.

Nearly one hundred thousand neurons all along
The canal alimentary form a network
Linking lifeforms that live there. The ‘vagabond’ nerve
Is the pathway they use to get what they deserve.
When they don’t, they can cause people to go berserk.
Neither they nor others know what the hell went wrong.

Managed mood modulations are magnificent.
Enhanced neuroplasticity and happiness
Comes about through the practice of yogic technique.
All those microbes we live with need their way to speak
In support of their function. Their will to express
Is for us the most vital and true of intent.
