3 poisons in Buddhism and their antidote (solution) on the Path to Liberation.

In the Buddhist teachings, the three poisons (of ignorance, attachment, and aversion) are the primary causes that keep sentient beings trapped in samsara. These three poisons are said to be the root of all of the other kleshas. The three poisons are represented in the hub of the wheel of life as a pig, a bird, and a snake (representing ignorance, attachment, and aversion, respectively).

The three poisons (Sanskrit: triviṣa; Tibetan: dug gsum) in the Mahayana tradition or the three unwholesome roots (Sanskrit: akuśala-mūla; Pāli: akusala-mūla) in the Theravada tradition are a Buddhist term that refers to the three root kleshas that lead to all negative states. These three states are delusion, also known as ignorance; greed or sensual attachment; and hatred or aversion.

The three wholesome mental factors that are identified as the opposites of the three poisons are:

• amoha (non-delusion) or paññā (wisdom)
• alobha (non-attachment) or dāna (generosity)
• adveṣa (non-hatred) or mettā (loving-kindness)

The Buddhist path considers these essential for liberation.

As Bhikkhu Bodhi states "For as long as one is entangled by craving, one remains bound in saṃsāra, the cycle of birth and death; but when all craving has been extirpated, one attains Nibbāna, deliverance from the cycle of birth and death."
