Jedi Religion is a very non-dogmatic, non-organized religion. As such, there are few if any rules that can be expected to be followed by all believers. However, this also allows for wisdom to be put forth by members of the community for believers to study, accept or reject as they see fit.
This particular list comes from Jedi Kidoshin of Jedisanctuary.org (now defunct) and is reproduced with permission. Commentary has been editted from Kidoshin's works as well.
1. Jedi believe in the Living Force.
Jedi believe in an invisible universal energy called ‘the Force’, also known as the 'Living Force', the 'good side', or the 'light side'. The Force is a living spiritual presence that surrounds us, penetrates us, and binds all the matter in the universe together. The Force is the soul of all living things; it exists everywhere. Jedi believe that Force allows people to have free will and choice, but that destiny also plays a part in their lives.
2. Jedi believe that there is a dark side but refuse to dwell on it.
Jedi believe that the dark side exists, but refuse to dwell on it, or follow it, or use it in any way. The dark side is a negative energy, also known as the ‘negative power’ or ‘dark energy’. The dark side is considered to be evil, negative, the opposite of good, and is never to be followed or used by the Jedi.
3. Jedi serve the Living Force.
Jedi serve the Living Force and never serve the dark side, in any way, shape or form. Jedi are serious about their service to the Force, and are not thrill seekers or adventure seekers. They are serious about following the Jedi teachings in their own lives, because the Jedi teachings lead to personal growth, and help them to be conscious of their connection to the Living Force, which is within.
4. Certain Jedi are stronger with the Force than others.
Jedi, in general, are individuals who are strong with the Force. The Force is with them. However, the Jedi believe that the Force is extra strong in certain Jedi, much more so than in others.
5. Jedi live in the present moment.
Jedi live in the here and now, and don't have stress about the future or the past. This isn't as easy as it might seem because the mind always rushes to the future or past. Contact with the Living Force always occurs in the present moment. The mind is our tool, and we need to stop the incessant thinking and mental chatter that comes from the mind in order to be conscious of the present moment, and to live in the present moment. We need to control the mind, and not let the mind control us.
6. Jedi can feel the Force.
Jedi are Force sensitive people, and are experts at feeling energy. Our senses and our scattered minds can block us from feeling the Force, but it's always there. Jedi are equally sensitive to dark energy or negative energy, and know how to avoid it and to protect themselves from it.
7. Jedi trust their feelings or intuitions.
Jedi are a 'feeling people' and believe in using and trusting their feelings and intuition. Jedi are intuitive and are in touch with the core of their being.
8. Jedi practice meditation to achieve a calm mind.
Meditation is clearly a part of the Jedi lifestyle. Jedi believe that a calm mind can be achieved through meditation and contemplation. Jedi need to meditate often in order to clear their minds. Our minds, like sponges, get contaminated from the world, and need to be cleaned out daily. We even absorb things from those who are around us, and from our environments, the food we eat, etc. so it's important to keep a calm, focused, clear mind and to meditate daily.
9. Jedi practice awareness and are mindful of their thoughts.
Jedi believe in practicing awareness and are mindful of their thoughts. Jedi keep their thoughts positive. A positive mental attitude is healthy for both the mind and body. Not every thought that 'pops' into our head is actually ours, since thoughts can originate from many sources across the Universe, and not just from our physical brain. We have to be able to discern the thoughts and remove the bad ones or negative, fear-based ones. Even the food we eat, and things we drink can influence our thoughts. So, we must always be mindful of our thoughts.
10. Jedi have patience.
Jedi choose to act with patience, and not to react with anger.
