How to see the mystery of the disappearance of past life memory from Buddhist scriptures

The memory of past lives has not disappeared (in the subtle subconscious), but it is not in the memory of the brain. The memory in the brain is the memory of the gross consciousness in this life. If you don't believe in thinking, as time goes on, unimportant memories in your brain will fade away and disappear.

Subtle subconscious (actually Arya's knowledge) is like throwing a stone on calm water, and you will see ripples in circles, which are very clear. At this time, we can say that we have eliminated the memory of Arya's discernment. If Pinghu suddenly becomes an ocean at this moment (metaphorically speaking, our greedy and persistent parting thoughts or memories left in our brains), of course, the waves are getting higher and higher, so who will see the inevitable ripples when we put a stone in it at this moment? This should be a truth.

In fact, the Buddhist scripture says that "Ayaya came first, and then became the Lord", and all kinds of karma can not be separated from it. So it will never leave us. We can't open its interior, which is caused by our own persistent separation. So our equality is the golden key to the subconscious. This is my understanding of this problem.
