What is the meaning of the issue of saying that there are occurrences that have no beginning?

Question:
He says: Honorable Shaykh, may Allah grant you success. I have been greatly confused by what Shaykh al-Islam Ibn Taymiyyah (may Allah have mercy on him) mentioned in his books regarding the issue of saying that there are occurrences that have no beginning. What is the meaning of that, especially since he was criticized for it? What is the truth in this matter?

Answer:
I see that you should not get involved in this, because you will not truly grasp its reality until you learn and study the Shaykh’s books thoroughly so that you know what he intended. As for you getting involved in this while you are still a beginner, it will only confuse you. And you say that it has confused you greatly. Yes, it has confused you greatly because you do not know. Yes, so I do not see that you should get involved with anything you have not yet reached. Yes.
