Water.

Vast amounts of H₂O

The ebb and flow,

Sweet/overpowering

The open sea :

Incomprehensible, Terrible

Human body microscopic

No power against the enormity

My presence tolerated

(Never welcomed)

In truth :hardly noticed

Vast being of happy goodness

Never changes

Sweet/overpowering

To dive in :

Incomprehensible, Impossible

But somehow occurs.

No power against the enormity

My presence welcomed

(Also noticed)
