The Noble Eightfold Path, is the path to avoid suffering. The Noble Eightfold Path is divided into three sections.  Sila (physical actions), Samadhi (meditative concentration of the mind), and Prajna (spiritual insight into the true nature of everything).   

Sila is a virtue, a good conduct, and morality.  These are based on two fundamental principles.  First principle which is of equality, which means all that is living is entirly equal.  The second principle which is of reciprocity.  Reciprocity is the "Golden Rule", do onto others as you would wish them to do onto you.
 Right Speech is when one speaks in a non hurtful, not exaggerated, truthful way.
Right Actions—Wholesome action, avoiding action that would do harm.
Right Livelihood—One's way of livelihood does not harm in any way oneself or others; directly or indirectly

Samadhi is concentration, meditation, and mental development. This training means to develop one's mind to the path of wisdom which leads you to personal freedom. To strengthen and control our minds you need mental development, inorder to maintain good conduct.
Right Effort/Exercise is when one makes an effort to improve. 
Right Mindfulness/Awareness is to have mental ability to see things for what they are with clear consciousness.
 Right Concentration/Meditatio means being aware of the present reality within oneself, without any craving or aversion.

Prajna is discerment, insight, wisdom, and enlightenment. This practice shows the true meaning of Bhuddhism.  You will gain more wisdom if you mind is pure and calm.
Right Understanding is understanding reality as it is, not just as it appears to be.                                                  Right Thoughts is the change in the pattern of thinking.
