“Generally seeking, in Buddhist literature, a negative emotion or thought is defined as ‘a state which causes disturbance within one’s mind’. These afflictive emotions and thoughts are factors that create unhappiness and turmoil within us. Emotion in general is not necessarily something negative. At a scientific conference which I attended along with many psychologists and neuroscientists, it was concluded that even Buddhas have emotions, according to the definition of emotion found in various scientific disciplines. So karma (infinite compassion or kindness) can be described as a kind of emotion.”
