If it's too serious to read, it's best to send it to the temple for the teachers to deal with, and don't throw it around. The Diamond Sutra says, "Where there are classics, there are buddhas. If you respect your disciples. "

In short, we should treat them with respect. Buddhist scriptures are Buddhist relics. If the Buddha comes in person, it is a great sin to deliberately blaspheme. If it is unintentional, you must sincerely repent.
