The Many Laws Of One

There are many conditions that the Torah imposes on the eating of the korban pesach.  One can't break bones, it generally was eaten with a group, it must be roasted and the animal must be roasted with all its parts together.  Why are there so many stipulations given to a liberating eating process?    Is there a common denominator to all of these laws or are they a random collection?  We already explained here, that the process of yetzias mitzraim was the process of Klal Yisroel developing into a nation.  A nation consists of people united together for a common goal.  The common theme behind all the rules pertaining to the eating of the passover lamb is that there is a focus on unity.  The commandment to roast is because through roasting the meat becomes shriveled and combined together.  That is why the lamb must be whole, its eaten in a group to encourage comradery, and no bones may be broken for that will take away from the wholeness.  The passover lamb teaches us that the בסיס for redemption is to be together, to become one nation (based upon Gevuros Hashem Ch. 35-36.)
