Agnosticism abides by the Humanist philosophy which stresses the inherent dignity and worth of each person, concern for the interests and welfare of human beings, and asserts that every individual has the capacity for self-actualization without the use of supernaturalism. The Buddha was a man who taught people about why life involves suffering and dissatisfaction and how to eliminate them. His teachings begin with The Four Noble Truths and The Eight Fold Path which teach how to minimize suffering and attain inner peace, also called enlightenment.
All life involves suffering and dissatisfaction.
Suffering and dissatisfaction originate in our desires and in our inability to recognize that all things are impermanent. Suffering can cease there is a state of being in which there is no suffering. This is Enlightenment or Nirvana. There is a way to achieve this state of being. Use communication for the good.
