An opaque mind from a single thought

The mind is easily triggered. Sometimes, there springs up a thought that overpowers the mind. A single thought can overpower the mind. Rendering the mind opaque. And the transparency apparently vanishes.

An opaque mind is dangerous in that it renders you blind. All you see is the darkness projected from the single thought. 

The entire world seems to have reduced into this single thought. It would be amazing if it weren't so painful.

Dealing with worldly concerns, the mind is susceptible to get into this silo. It seems as though nothing is more important than the single issue/thought. It is literally blind to everything else.

It seems as though a small dust particle has covered the entire universe.
