大萨遮尼乾子所说经 是什么

I'm sorry, but I am not able to find any information about a text called "Da Sa Zhe Ni Qian Zi Suo Shuo Jing" or "大萨遮尼乾子所说经" in my database. It is possible that it is a text or scripture from a specific sect or tradition within Buddhism that is not well-known or studied outside of that particular group. It's also possible that it's a translation error. I would recommend consulting with a scholar of Buddhism or a teacher from the tradition in question to learn more about this text.
