The old Pali texts contain three lists of evils and factors which obstruct meditation and moral perfection. The list of five 'hindrances' (nivaranas) consists of sensuous desire, ill will, sloth and torpor, restlessness and sceptical doubt. These hindrances blind man's mental vision and make concentration difficult. The list of ten 'fetters' (sanyojanas), which bind beings to sansara, comprises the following: belief in a permanent individuality, sceptical doubt, belief in the efficacy of mere moral observances and rituals, sensual passion, ill will, desire for existence in the material world, desire for existence in the immaterial world, conceit, restlessness and nescience.
