In plain words

And it is said elsewhere too: Bewilderment, fear, dejection, sleep, sloth, injury, old age, sorrow, hunger, thirst, meanness, anger, unbelief, ignorance, envy, cruelty, stupidity, shamelessness, baseness, arrogance and unevenness — these belong to the strand of darkness. Craving, affection, passion, greed, violence, lust, staring about, jealousy, desire, unsteadiness, fickleness, the wish to seize, the getting of wealth, favouring of friends, dependence upon possessions, hatred toward the objects of sense that are not wanted and clinging to those that are — these belong to the strand of passion. Filled with these and overcome by them, this elemental self comes to have many forms — comes to have them indeed.
