You might feel slightly disenchanted with samsara, develop a vague determination to be free of it, and take on the semblance of a serious Dharma student to the point that ordinary folk are quite impressed, and want to be your patron and disciples. But at that point, unless you take a very rigorous look at yourself, you could easily start thinking you really are as other people see you. Puffed up with pride, you get completely carried away by appearances and start to think that you can do whatever you want.
