"taught the Eightfold Path"

In the essay "Buddhism Meets Western Science", Gay Watson explains:

"Buddhism has always been concerned with feelings, emotions, sensations, and cognition. The Buddha points both to cognitive and emotional causes of suffering. The emotional cause is desire and its negative opposite, aversion. The cognitive cause is ignorance of the way things truly occur, or of three marks of existence: that all things are unsatisfactory, impermanent, and without essential self."

 

The Noble Eightfold Path is the fourth of the Buddha's Four Noble Truths and is the way leading to the end of suffering (dukkha) and the achievement of self-awakening. Also known as the Middle Path or Middle Way it is often represented by a dharma wheel (dharmacakra), with eight spokes.
