Times of general calamity and confusion create great minds. The purest ore is produced from the hottest furnace, and the brightest thunderbolt is elicited from the darkest storms. - Charles Caleb Colton
The colour of fear is never dark or black; it has the colour of thunderbolt; usually white, but can appear in different hues depending on how the fear travels through to get inside your heart - Munia Khan
Be mild with the mild, shrewd with the crafty, confiding to the honest, rough to the ruffian, and a thunderbolt to the liar. But in all this, never be unmindful of your own dignity. - John Brown
