Did Buddha go to her mother or the mother went to him?

I finished studying the Chinese Sinhala Vinaya Commentary days ago and I was going to mention this.

If it belongs to Abhayagiri Monastery I read that they believed the mother came with others gods to learn the Abhidhamma.

It’s interesting to read another tradition. But makes you think if that was the first tradition.

Don’t we go to the doctor if we are sick?

Unfortunately I didn’t take screenshot. The books are here
