Buddhist scriptures are what the Buddha said for all living beings in the Nine Dharma Realms to escape from reincarnation until they achieve Buddhahood. Of course, they cannot be discarded casually. If the poster no longer needs it, then send it to the temple and hand it over to the monk master. That's it. If you throw it away casually, I'm afraid there will be Dharma Protector Dragon Heaven who will punish you. Wish you good luck with your hands together, Amitabha.
In terms of respecting the three treasures of Buddha, Dharma and Sangha, this is not about "don't be attached". The problem is to be extra respectful, because "one point of respect will lead to one point of blessing and wisdom, and great respect will lead to a lot of blessing and wisdom." To give an inappropriate example, if someone takes a photo of a senior brother's parents and throws it casually in the toilet Or other dirty places, then can this senior brother say, "Don't be attached, it's just a photo." Is that okay? What's more, Buddhist scriptures are a compass that can save all suffering sentient beings from the suffering of reincarnation. We can only escape from the suffering of life and death by relying on the teachings of Buddhist scriptures and practicing according to the Dharma. It's too late to bow and respect, so how can we talk about "not being attached"? If you are not a truly enlightened Zen practitioner, it is best not to casually learn to say things like "There is nothing in the first place, so where is the dust", because that is not the realm of ordinary people. Understand what true Zen is, otherwise you are just parroting it. I would like to ask, if you are "non-attached" to the Three Jewels of Buddhism, Dharma and Sangha, then when you face great pain or death, can you easily say "life and death are Nirvana, and troubles are Bodhi"? You will still be worried and in endless pain. How about shouting at the sky and grabbing the earth?
As for the handling of the Buddhist scriptures you have written, it is best to send them to the temple to be handled by the monks. They will do it more rationally and legally than you. If you burn or otherwise handle it yourself, I am afraid that it will There will be some inappropriate places.
