The role of different souls in the overall repair: variations in the fortunes of the righteous are rooted in the hidden connection of MaH and BaN.
The repair allotted as the task of each individual soul stems from the way this interconnection of MaH and BaN is arranged, and this is the root cause of why in some cases the righteous enjoy a good life while in other cases they suffer. From the way the souls are rooted in the Partzufim of Atzilut there appears to be no valid reason for this. But the truth is that the root of this mystery lies in this hidden connection.
Further to our explanation of this concealed root, we will now discuss the way it affects the governmental order.
The repair allotted as the task of each individual soul... The Supreme Mind did not create more souls than were necessary for the task, for He calculated everything - the human form as the key to the way man's service and the commandments of the Torah are ordered, and the human form as the key to the way the souls are ordered. Thus each soul has its own root repair to carry out, and this contributes to the successive repair of all aspects of existence according to what is allotted to that soul.
...stems from the way this interconnection of MaH and BaN is arranged... For the souls are rooted in these levels that we have been discussing ("the Yechidah is from Adam Kadmon" - Shaarey Kedushah 3:2), and it is from there that they receive their mission each according to its particular root. If this is the level where the souls are rooted, it is because because the entire governmental order operates first and foremost through and for the souls, and from them it extends to all the different creations and all the worlds. (The entire creation serves man, and therefore the creation is arranged according to the service required of the souls.)
...and this is the root cause of why in some cases the righteous enjoy a good life while in other cases they suffer. On that level there is a logically necessary reason why one righteous individual may have a good life while another suffers. This is the concept of "the fortune (מזל, mazal) of the hour" that affects people's destiny, for this depends on the individual root of the soul but not its individual root in Atzilut. (The Mazal - the soul's share in the overall service - depends upon the interconnections of MaH and BaN that are rooted in the Head that is Unknown, but not on Atzilut, where the service is founded on the principle of merit, reward and punishment.)
From the way the souls are rooted in the Partzufim of Atzilut... For just as there are two orders of government - the concealed order rooted in the Head that is Unknown and the revealed order of Atzilut - so the souls are rooted in both of them. Initially they were rooted in the hidden level, and afterwards they enter and take root in the revealed order of Atzilut.
...there appears to be no valid reason for this... This was why Moses had difficulty with the suffering of the righteous, and moreover the Holy One blessed be He answered him: "I will be gracious to whom I will be gracious" (Exodus 33:19) - even though he may not be worthy (see Brachot 7a). For according to the root of the soul in Atzilut they did not deserve this lot. But the truth is that the root of this mystery lies in this hidden connection.
