The three principles of Jainism also known as Triratnas or three gems are:

• Right faith- belief in the teachings and wisdom of Mahavira
• Right knowledge- acceptance of the theory that there is no God and that the world has been existing without a creator and that all objects possess a soul
• Right conduct- observance of the 5 doctrines–
  • Not to injure life
  • Not to lie
  • Not to steal
  • Not to acquire property
  • Not to lead an immoral life

Other teachings:

• Strictly follow the doctrine of ahimsa. It regarded that all objects, both animate and inanimate, have souls and possess life and feel pain when they are injured
• Mahavira rejected the authority of the Vedas and objected to the Vedic rituals. He advocated a very holy and ethical code of life
• Even the practice of agriculture was considered sinful as it causes injury to the earth, worms and animals
• To carry out the doctrine pf asceticism and renunciation to extreme lengths by the practice of starvation, nudity and other forms of self-torture
