Why Shiva created the universe for Kshetrajñahah?

Question

We find

It has been ascertained that the earth and other objects are the created ones (they are basically products) and ascertained that the creator of all these products is Isvara. Since that Isvara is a Supreme Being associated with perpetual contentment (nitya trupta), the created objects could be of no use to Him. Nor the created worlds could utilize themselves, since they are non-intelligent. Since Lord Siva is with such a greatness and lordship, he cannot perform purposeless actions; He cannot create purposeless objects. Therefore, through the process of elimination, it is ascertained that the creative function and the created worlds are neither for their own sake nor for the ever-content Lord who has created all these, but only for an intelligent being existing apart from the created and the Creator. That intelligent being is known as the kshetrajñahah. Mregendra āgama 6.2.

Abhinavgupta provides following explanation about kshetrajñahah.

The field (kshetra) is the body of worldly beings where the seed of action is nurtured. In the case of worldly beings the embodied self (jivātma) is called the knower of the field (kshetrajñahah) , who remains polluted by temporary impurities. However, in the case of enlightened ones, the embodied self is called kshetra.

Therefore it is clearly explained, Lord Shiva has not created the universe for his own, he created for Kshetrajñahah. But why would Shiva create the universe for them?

Answer 1

The chapter of that Mrigendra Aagama is talking about 'Pashu Lakshanam' or the 'Nature of the Bound Soul', so the Kshetrajna there refers to Individual souls.

Why would Shiva create the universe for them ?

In the Shaiva Siddhantam there is purpose for the creation of universe. However in the Vedanta, creation by Brahman is just considered purposeless and solely Leela.

This is given by the reasoning of this in the Aagama:

Nor the created worlds could utilize themselves, since they are non-intelligent. Since Lord Siva is with such a greatness and lordship, he cannot perform purposeless actions; He cannot create purposeless objects.

So, the reason given is that Lord Shiva won't create purposeless objects like unintelligent matter just for play. There must be some reason. And the reason is individual soul by nature is composed of Anava impurity and when that impurity is removed then only soul attains Supreme Shivam state. So, Shiva has purpose to create Universe and it's because he wants that souls get rid of Anava and attain Supreme state:

For the creation of the world as inclusive of body(tanu), instrument(karana), sources of enjoyments (bhoga) and so forth, soul is the necessitating factor. Even while expounding the nature of Siva, the specific nature of the soul has been told. The soul, in its embodied state, is with a knowledge shrouded by the darkness of anava-mala. It is not independent. Such characteristics were expressed there. Now, the essential nature of the soul is succinctly established. (Mrigendra Aagama 6.1)
