The following is a message that I received about a non-jew who was interested in "observing" pesach this year, and my response. I'd like to point out 2 things:

 First is that it seems rather odd that a non-jew would want to celebrate pesach,  It is like a south african celebrating Cinco DeMayo. 

The second is that I'm not any type of authority on the responsibilities of non-jews in the world, I'm only a simple jew sharing some of the little knowledge that I have gleaned. Do not take any of what you are about to read too seriously without first checking up on its accuracy  from a more reliable source.

We have the tradition that g-d, our creator (yours and mine) made the jewish people along with many other nations (peoples) , each nation has its own unique purpose. To us jews he gave special instructions to live our lives, in a way that will fit our spiritual needs best. Following the path he created for us will lead to growth and elevation on all realms, the spiritual , as will as the the world that we can experience with our physical senses. But if we follow the path set for one of the other nations it will cause us harm. We have the tradition ( for over 3k years) that if some one from one of the other nations tries to follow the path designated for the jewish people then he will more than likely cause him self more harm than good.

Let me give an example. One day a week jews rest from all creative activity, because we have specific instructions from The creator to do so, and for us it is a great thing "in his eyes*" . But if a non-jew does no creative work for a whole day , what has he done ? Wasted a whole day. He had no instructions to do so. Maybe that was the day he was supposed to discover the cure for cancer, or foil a terrorist plot, or meet his wife. Even though he had the best intentions, to become closer to his creator he has in-fact done harm to him self , as well as possibly the whole world.

I'm sure you can easily understand this. 

It is for example I'm sure you understand that some people are more fitted for certain jobs. If a world renowned brain surgeon, with the best intentions, tried to design a nuclear power-plant to provide power to a poor third world country, the results would be disastrous. And of course the same thing would apply in reverse, I wouldn't want a nuclear engineer performing brain surgery on me. Obviously they would cause damage, but we might ignore is that the time that they spent causing damage could have been used to cause benefit .  Spirituality is much the same, we all have "spiritual aptitude"  or "spiritual talents" for different tasks. 

With that said when some one without jewish "spiritual talents" tries to do to the tasks designated for jews, he is  not doing him self or the world any kindness.  ( the same thing  of course applies when a jew tries to do a task that requires the "spiritual-talents" of a different nation. )

One, out of the many tasks that requires specifically jewish "spiritual talents" is keeping passover.  While I can understand why some one who is "exploring his religious horizons" would be interested in exploring one of the foundations of the jewish faith, you should know that it will do you more harm than good. 

One of the great jewish sages teaches : (note that this is a translation from the original language, and as with translations much of the meaning was lost)

So what are these 7 laws ?

This is, of course an over simplification of each of the laws, there are many details to exactly what each one means, and how exactly to "guard" each law. If you (hopefully) have interest let me know and I'll find you more information, or direct you to some one else who can help.
