According to Buddhism, the three negative emotions that cause disease are ignorance, hatred and desire. Accordingly physical sickness are classified into three main types.
• Disorders of desire (Ayurvedic equivalent of Vata imbalance): These are due to disharmony of the wind or energy. The seed of these disorders are located in the lower part of the body. It has cold preferences and is affected by mental desires. In this, the person mainly suffers from the disorders of movement functions.
• Disorders of hatred (Ayurveda equivalent of Pitta imbalance): It is due to disharmony of the bile. The seed of these disorders is centered in the middle and upper part of the body and is caused by the mental emotion of hate. The person suffers from metabolic and digestive abnormalities.
• Disorders of ignorance (Ayurveda equivalent of Kapha imbalance): It is due to the disharmony of phlegm, the seed of which is generally centered in the chest or in the head and the disorder is cold in nature. It is caused by the mental emotion of ignorance.
Desire, hatred and ignorance are the main negativities mentioned in Buddha’s philosophy. They are all produced in the mind, and once produced they behave like a slow poison. The Udanavarga once said, “From iron appears rust, and rust eats the iron”, “Likewise, the careless actions (karma) that we perform lead us to hellish lives.
According to the other scriptures, six afflictions are most troublesome, namely ignorance, hatred, desire, miserliness, jealousy and arrogance. Patience is the most potent virtue a person can acquire. According to the Shanti Deva, “There is no evil like hatred, and there is no fortitude like patience. Therefore, dedicate your life to the practice of patience.”
Bhagvad Gita classifies the enemies as Kama, Krodha, Lobha, Moha and Ahankara; of these, Kama, Lobha and Ahankara, are the three gateways to hell.
