question ①
> Is it OK for ordinary amateurs to recite sutras?
It's fine. Whether you're an ordinary person or a monk, nothing changes. Depending on the content of the sutras, it may be difficult to understand, and it may cause suffering due to soliloquy, but if you just chant it, I don't think there's any problem.
Sutras are a compilation of the Buddha's words (teachings) or contents accepted by those who have listened to the Buddha's words (teachings). It's not a spell, so it's fine.
question ②
> If an ordinary amateur recites the Heart Sutra somewhere before, a ghost will come by and it's dangerous. I heard something like that, is that true?
It's not true.
question ③
> Also, are there any sutras that have an exorcising effect or sutras that have an inspirational effect?
It's not there.
Question ②③ assumes that ghosts exist, isn't it?
There may be a pattern where assumptions are resolved by assumptions when people who assume that ghosts exist assume that they will disappear due to sutras.
Alternatively, there may also be a pattern where people who assume that ghosts exist notice that ghosts are there depending on the content of the sutras, and their fear of ghosts is resolved. It may be possible to call these patterns exorcism, but I personally think this is an unfavorable expression.
“Things are based on the heart, centered around the mind, and created by the heart. If they talk or go with an unclean heart, suffering follows that person. -Like wheels following in the footsteps of a (cow) running a car.” Dhammapada 1
This is also a sutra.
The presence or absence of ghosts cannot be determined unless proven scientifically. However, it's not about scientific presence or absence; people who assume they have can see things they don't have, and they actually suffer from what they don't have. The Buddha suppresses it as “based on the heart.”
That's why we must look at things with the right eyes so as not to suffer.
It must be like this, it must be like this, I want it to be like this
It is dangerous if this “thought” takes precedence. What do you think about first? Let's check the “facts” clearly.
Be careful not to trust dangerous knowledge.
