stone that the builder refused 

1.

The visual
The inspiration
That made lady sing the blues

2.

the spark that makes your idea bright
The same spark
that lights the dark
So that you can know your left from your right

3.
the ballot in your box
The bullet in your gun
The inner glow that lets you know
To call your brother son
The story that just begun
The promise of what's to come

4. The opening line to the Boondocks theme song, "I am the stone that the builder refused"

I am the stone that the builder refused
I am the visual
The inspiration
That made lady sing the blues
Etc...

Never put a stone on the table. 

Daniel's principle states that when one puts out a heavy topic at the communal table, one is either seeking attention or trying to instigate trouble.

stone-thrower in the glasshouse 

One who acts without thinking about the consequences one’s action might have on others whose similar action might have on one; one who blames others for the fault which one has oneself.

He is a stone-thrower in the glasshouse. He always parks his car in front of his neighbor’s house (in a style called rockstar parking), blocking the neighbor’s car. What would happen to him if his neighbor also did the same?

the sharpest corner of a large stone

the sharpest corner of a large stone (adage) - a proverb referring to the best ability of a person.

When it's about to hit you, and it's too large to escape from, you mainly try to get away from the sharpest corner of a large stone. Similarly, you should only show the greatest talents possessed by you to others—not the dumbest ones.
