Basic Meaning
Often referred to as poisons, these are a class of disturbing or disruptive emotional states that, when aroused, negatively affect or taint the mind.
See page 438: In Sanskrit, “afflictions,” or “defilements”; mental factors that disturb the mind and incite unwholesome (akuśala) deeds of body, speech, and/or mind. In order to be liberated from rebirth, the kleśa and the actions they incite must be controlled and finally eliminated. A typical Standard list of kleśa includes the so-called three poisons (trjviṣa) of greed or sensuality (rāga or lobha), hatred or aversion (dveṣa), and delusion (moha).
