There are seven principals to a Noahide life, or the principals which Noah and his family lived by. These principals were natural to them and all other laws or guides emanated from them.

“When one loves deeply, one avoids harm to others, yet wishes to protect them with G_d’s/Hashem’s help.

Our interpretation of the principals in today’s age:
– – – Avoid worship of idols
– – – Avoid using G_d’s/Hashem’s name to curse or promise by
– – – Encourage a community which is fair to others
– – – Avoid taking the life of another human
– – – Avoid a lustful life and treat intimacy as a unique bond
– – – Avoid taking from others which is unearned
– – – Avoid eating anything which has not been carefully prepared

The 7 Laws as referenced by other organizations:

– – – Do not profane G‑d’s Oneness in any way. 
Acknowledge that there is a single G‑d who cares about what we are doing and desires that we take care of His world.
– – – Do not curse your Creator.
No matter how angry you may be, do not take it out verbally against your Creator.
– – – Do not murder
The value of human life cannot be measured. To destroy a single human life is to destroy the entire world—because, for that person, the world has ceased to exist. It follows that by sustaining a single human life, you are sustaining an entire universe.
– – – Do not eat a limb of a living animal.
Respect the life of all G‑d’s creatures. As intelligent beings, we have a duty not to cause undue pain to other creatures. 
– – – Do not steal
Whatever benefits you receive in this world, make sure that none of them are at the unfair expense of someone else.
– – – Harness and channel the human libido.
Incest, adultery, rape and homosexual relations are forbidden. 
The family unit is the foundation of human society. Sexuality is the fountain of life and so nothing is more holy than the sexual act. So, too, when abused, nothing can be more debasing and destructive to the human being.
– – – Establish courts of law and ensure justice in our world.
With every small act of justice, we are restoring harmony to our world, synchronizing it with a supernal order. That is why we must keep the laws established by our government for the country’s stability and harmony.

Human kind will always provide an interpretation which suits their lifestyle and needs. So how can one tell which interpretation is right? – If one’s center of life is founded in love and reflects deeds which is helpful to others and not self serving, then the meaning stated should resonate within and have a sense of clarity in one’s own mind. “It just makes sense.”
