Śaṅkarācārya's commentary

Vulgar: quite uncultured in manners (buddhi); he is like a child. Unbending: not bowing like a stick to anybody. Deceptive: concealing his real power. Wicked: setting others at variance with each other. Indolent: not doing even what ought to be done. Desponding: always depressed in spirit. Procrastinating: postponing duties too long, always sluggish. He cannot do, even in a month, what ought to be done today or tomorrow.
