The subtle nature of Guanyin Bodhisattva.
According to the scripture, the Buddha was talking about a good man, and this six-character Daming Dalagni knew the subtle nature of the Mahasa Bodhisattva. Know how to get rid of it.
I remember there was such a metaphor in the Buddhist scriptures.
With the magical power of the Buddha, the number of all raindrops in an area can be measured by the difference of one thought 12, but the Buddha can't measure the merits of reading a six-character mantra.
It can be seen that the power of this subtle impression of Daming is really unspeakable, unpredictable and unknowable.
For example, those who recite this mantra wholeheartedly can get rid of the seven generations of races, even the worms in their bellies, and get the fruits of bodhisattvas who can't turn back, etc., but this is a subtle and unpredictable impression, so no matter how you explain it, it is just a drop in the bucket.
