I have a problem with advaita

Hello to all of you brothers and sisters. I have never written a post on reddit but I have had an unresolvable concern for weeks and I think this is the most appropriate place. I am from a Spanish-speaking country and I do not speak English very well so I beg you to forgive my spelling. Also, I am very new to your doctrine and foreign to Hindu culture, so please forgive the mistakes. I will talk about God in the third person to solve the problems of language, but always assuming that there is no God as a third person.

To give a brief personal context: I am Catholic, but I have always been concerned about the duality of Christianity and I sought other religious paths that would help me better understand God. I have found and assimilated some teachings of Advaita Vedanta, but nevertheless there is a problem that prevents me from agreeing and completely breaks the scheme for me. I am not writing this with a proselytizing zeal or as something merely intellectual, I really want to understand but I have this problem and I cannot find any solution.

I understand (in a rational and supra-rational way) that God is all that is, that our being is the being of God, and that there is nothing in us that is not God. But this is my problem with advaita: The reason why God creates. Why God generates an illusory experience

From what I have read, some say that this question is irrelevant and should not be asked. If you wake up and see that your house is on fire, you don't ask why, but try to get out. But appealing to chance is the worst thing you can do, because you are running somewhere without knowing where you are going. If God has deliberately set your house on fire, you should burn to death. I have also read that the meaninglessness of the generation of human dreams can be compared metaphorically to the generation of the experience of multiplicity by God. This analogy is even worse, because human dreams assumes thousands of bodily, mental and spiritual determinations and circumstances that God does not have. On the other hand, I have also read about the concept of lila, and I like this concept very much, but it seems to me to go against the Advaita teachings on suffering and the experience of multiplicity.

This question is the central question, everything we can consider about life and Reality is centered on this. My point is that this question is the central question, everything we can consider about life and Reality is centered on this. If the experience of multiplicity has been generated by something, even if it is a game for no other reason than the game itself, there are a whole series of repercussions of enormous importance.

I accept that form is pure contingency and that the only real thing is God, "Everything passes, only God remains." But God is generating in this eternal instant the entire colossal experience of multiplicity. God is generating the experience of multiplicity, whatever the reason, whether with or without will, whatever the reason, God is generating the experience of multiplicity, and because it is created by God it must be embraced without judgment

So, based on the idea that God generates the experience of multiplicity for a reason, the following 5 points:

1. This contingency is not absurd or fortuitous. God has generated for a reason, and even if it is for fun, this implies that this contingency is necessary, and that we should not deny or overcome the individual experience, but live it, because all multiplicity is the creative work of God. We should not live denying or fleeing from the experience of multiplicity, but play with it, and that implies action
2. Action is something inherently positive. Action is what God has generated when he generates in this eternal instant the entire experience of multiplicity. If it is by lila, action is to the divine game what the ball is to a football match. If it is not by lila, action is that which is constant in the experience of the multiplicity that God is generating. We must enter into the experience, get dirty with mud, sweat, love, bleed and develop with total decision the experience of individualized biological life. To live, which is equivalent to doing, based on the fact that God is all that there is, and that this "illusion" has been generated by God, and that therefore we should not be afraid to do and to live. In this I especially emphasize the corporal, sensitive experience: the five senses and the corporal movement as an essential part in the expression of the experience of multiplicity. Concepts such as “gross body” imply a judgment of our divine action in generating experience; matter and physicality are part of God.
3. Attachment is part of the experience of multiplicity. Loving, obsessing, crying, being sad, desiring and wanting are all part of the experience of multiplicity as it has been generated by God. Living dispassionately goes against all the bodily and mental dispositions that God has generated in this experience of multiplicity. There is no contradiction between my knowing myself totally as my ego (with my name, my body, and all the contingent relationships that constitute me) and at the same time knowing myself as God. I enjoy the experience of multiplicity as it is, because I am God himself who in the divine game creates out of pure joy. Without seeking to alienate myself from the fickle experience of multiplicity and without ever forgetting that I am in essence the only Being. The experience of multiplicity necessarily includes attachment and desire, virtue is not in dispassion, but in taking this attachment always without forgetting that God is all that is.
4. The idea that suffering is negative and avoidable is an axiom that comes from God having generated experience without purpose. This is another idea that I have read from many Advaitas (and Hindus and Buddhists in general). The goal of our life cannot be to avoid suffering. Physical and psychological suffering is part of the experience of multiplicity; we must not deny it, but accept it, because God has generated it along with the entire experience of multiplicity. We must give thanks for it, thanks for the joy and thanks for the pain.
5. In conclusion, if God is generating the experience of multiplicity, we must live surrendered to the experience, generating experience through doing, and playing in multiplicity always knowing that God is what He is and seeing our being in all beings and all beings in our only being. Knowing that there is nothing to gain or lose, that we must not go anywhere, nor look for anything, nor ask for anything, we must not avoid anything, not even suffering. We are God generating the experience of multiplicity, and denying God is as negative as denying the experience that God is generating.
