Jainism as it is described by Wikipedia.com:

Jainism differs from other religions in its concept of a god. Jainism regards every living soul as potentially divine. When the soul sheds its karmic bonds completely, it attains God-consciousness. It prescribes a path of non-violence to progress the soul to this ultimate goal.

About.com explained it as:

Jainism is a non-theistic religion that developed from Hinduism in the Indian sub-continent at about the same time as Buddhism. Jainism comes from a Sanskrit verb ji, ‘to conquer’. Jains practice ascetism.

EJainism.com says:

The ‘Jains’ are the followers of the Jinas. ‘Jina’ literally means ‘Conqueror.’ He who has conquered love and hate, pleasure and pain, attachment and aversion, and has thereby freed `his’ soul from the karmas obscuring knowledge, perception, truth, and ability, is a Jina. The Jains refer to the Jina as God. They teach us to reduce vices like rãg (attachment), dvesh (aversion), krodh (anger), màn (pride), mãyã (deceit) and lobh (greed).

Every individual is a JainJi who practices following principles:

  • Non-violence (Ahimsa) – to cause no harm to living beings.
  • Truth (Satya) – to always speak the truth in a harmless manner.
  • Non-stealing (Asteya) – to not take anything that is not willingly given.
  • Celibacy (Brahmacarya) – to not indulge in sensual pleasures.
  • Non-possession (Aparigraha) – to detach from people, places, and material things.
