The landlord pressed the wrong button. It should be "a foolish idea" which means "prajna"; A wise thought is Prajna. This sentence comes from the Prajna Two Classics in the Tanjing. As an adverb here, it is equivalent to "just right" or "then", indicating that the former thing happened and the latter thing happened immediately. Let's look at the word "Prajna" again. "Prajna" is a Sanskrit transliteration, a Buddhist term, which refers to the wisdom of knowing everything truthfully. It is one of the "six degrees" and the special wisdom needed to achieve the realm of "three pity and three bodhi", which is not possessed by the secular. In order to distinguish it from wisdom in general, the ancients adopted transliteration, which is pronounced as "elephant (b not)" and "one thought" means a very short time in Buddhist scriptures. "Stupidity" here does not mean a person's intellectual stupidity and stupidity. Buddhism refers to people who are obsessed with the illusion of the phenomenon world and don't want to get rid of it. They are idiots. Understand the meaning of "namely", "prajnaparamita", "one thought" and "stupid", and this sentence is easy to understand. Its original intention in the altar sutra is: any thought becomes a fool, and Prajna wisdom will be cut off immediately; When any thought is enlightened, Prajna wisdom will be born immediately.
As for what a man's QQ signature means, I can only make a subjective inference to the landlord with my little QQ knowledge (I seldom go to QQ at ordinary times). QQ signature is generally used as a platform to show your personality. But nowadays, it is mostly used to create riddles for others to guess "answers", or to innuendo, to criticize others, or to dance with Xiangzhuang. I think there are only two situations when a man uses this sentence: first, he is a Buddhist or a Buddhist enthusiast. He really wants to show his personality and make more friends with Buddhist researchers. Secondly, he pointed at something and vaguely wanted to express a meaning. Since you asked, it means that someone cares about his signature, so it is meaningless for us to analyze whether it is the first case. What does he mean if only the second case is analyzed? Is he saying that he was cheated by some girl because of his stupidity? Or did you have a quarrel with your girlfriend, but you didn't want to take the initiative to admit your mistake and coax her to make up, so you euphemistically expressed your persistence in this way? It is impossible to judge the various problems of the conditions given by the landlord. What is the specific situation is only known to you, and you have to analyze it yourself. Of course, you can refer to my above analysis ideas for inference.
Although it was a day ago, maybe your problem has been solved, but I still hope it will help you!
