Why go through the Birth/Death cycle?

It is said that: Paramathma is full of compassion and suffers due to the sufferings of the Jeevathmas in this world. His goal is to have us all with Him after relieving each and every one from worldly bondage.

A question that may arise is: So, why cant He just have us with Him in the first place? Why does He have to let us into this world and then, have us all back?

Now, let us try to answer this question. When we have a jewel in our posession, do we want to just keep it locked inside, or do we want to bring it out, and wear it for everyone else to see? When a jewel is kept without being used, it just accumulates dust and even loses its glitter by becoming dirty. On the other hand, if it is properly used frequently, it glitters and shines and pleases everyone. Thus the true nature of a jewel (its glitter and shine) comes out only when it is outside in the light.

Jeevathmas are Paramathma's jewels. Jeevathmas belong to and only to the Paramathma (Lord Sriman Narayana). Only when Jeevathmas are let out into this world, their true nature comes out - only by coming to this world, the azhwars were able to pour their hearts out in the Divya Prabandhams, the philanthropists are able to perform their benevolent deeds etc. Thus, by periodically letting Jeevathmas into this world, He constantly purifies us and takes us back to Him.

Of course, when He lets us into this world, there is the big chance that we lose focus and get distracted by physical/material things, thereby tarnishing our true nature of doing only things that please Him. This is similar to a jewel being used for the wrong purpose like adorning the sole of a shoe. Only to prevent this from happening, He constantly reminds us of our goal by means of the teachings in the Vedas, the examples set forth in His Avatars, the concise and easily understood teachings in the Divya Prabandhams and last but not the least, the words of our Acharyas. Let us focus on our goal and increase the glitter in us (His jewels) and make Him happy.
