The doer who is unsteady, not collected; vulgar, of an utterly unrefined understanding, like a child; stubborn, who like a staff bends to no one; deceitful, a trickster who hides his powers; spiteful, bent on cutting others down; lazy, disinclined to act even in his duties; despondent, always sunk in low spirits; and a procrastinator, who draws out his tasks endlessly, of a forever sluggish nature, so that what should be done today or tomorrow he does not do even in a month; such a doer is called of tamas.
