No. The Absolute did not become anything. All 'becoming' is only appearance. It is only 'as if' it became so:*
Brahman and Maya (edited)
Brahman has “become” the world through maya:
Brahman is absolutely real and formless. But then, there must be something with that Brahman to be able to ‘become’ this world of forms. This power is called maya. Maya is there because this is how Brahman is. We don’t ask, “Why is there maya?” because we don’t say that there is maya. We say that there is only Brahman. Brahman ‘plus something’ doesn’t exist at all.
The world is Brahman. If Brahman is limitless consciousness, without any particular form, then how could it become this world of forms? It did not. Consciousness continues to be, without any change. The gold has not become a chain. Only if it becomes a chain do I have to answer the question, “How did it become a chain?” Gold continues to be gold. Once you understand that clearly, then we can say Brahman has “become” the world through maya.
Everything becomes ‘as though’
An individual, due to not knowing this fact, is under the veil of maya. He is called the jva. Until he calls the bluff, inquires into the reality, he continues to be a jiva. And once he understands the meaning of the sentence 'you are that' (tat tvam asi) very thoroughly, he is free and whole. He is no longer bound by action (karma) etc. The whole performs no action; all action is ‘as though’**. Everything becomes ‘as though’. The whole remains the whole.
Swami Dayananda Saraswati
*as fluctuations in the Unified Field 'becomes' the (virtual) mass of the atom. It does not. Atoms remain as 'possibility'.
**'as though' = 'as if'

When I say that the Ultimate Reality lies beyond Logic, Reason, and Analysis, I am saying it cannot be reached via the limited rational mind. But I am not saying it lies in some mysterious nebulous la la land 'out there'. It is forever and always right here, right now.
