The Surangama Sutra: The Influence of Demons on Spiritual Practitioners Greedy for Spiritual Powers or Profound Emptiness, Part 1 of 5, Dec.30, 2018

So there were many kinds of ghosts that you have heard from the Buddha. They might appear to look holy and they may repeat some of the Buddha’s sutras. Especially in those times, it was not easy to get the real teaching from the Buddha. Then you just rely on whoever knows it and transmits it to you. So the ghosts can say anything. That’s why they lead people astray. That’s why people become crazy or break all the precepts, which are very important when you are still in this physical world. From today, from now on, you try to speak positively. It’s all determined by you. Just say, “Will do.” Like that. Or something positive.
