(Clearwisdom.net) For the past two days, my spirits have been very low and I have been very tired. I took two-hour naps at noon on both days, but was still very tired by 9:00 p.m. I had been asleep for about two hours and was dreaming, when suddenly I felt a spirit wrap up my body, and I could not move. I experienced such phenomena many times before. I was determined with one thought: I must get up, and not let it tie me up. I struggled for several minutes and finally got up.
I started sending forth righteous thoughts as soon as I got up, and sought inwards. Suddenly I enlightened that I had a big attachment: I liked to listen to sad popular music, and liked to sing along. I sank into the sad mood of those songs and thought that I had sung very well. How terrifying! Master said, "Some qigong masters have written books, but so what. You know what, their books are such a mess they're like those things they practice--snakes, foxes, and weasels, they're all in there. When you read those books that stuff will jump out from the words." ("Spirit Possession," Zhuan Falun)."
All of the writers and composers of these songs are ordinary people. Some of these songs carry very bad messages. Liking to listen to popular music in itself is an attachment, and if the writer had spirit possession, then when you listen to and sing these songs, you could incur spirit possession yourself. I have been singing these sad songs a lot lately, and even bragging in front of my friends; no wonder I have felt so low.
After sending forth righteous thoughts, I felt much better. I deleted all of the popular music that I had stored in my computer, and will not sing or listen to these songs from now on.
The above is my personal understanding. Please correct me.
