It should be your father's dream to have such an accidental dream. The bodhisattva in the dream is a Tibetan bodhisattva or Guanyin bodhisattva and Xiaojin couple. The Tibetan Bodhisattva holds a Buddhist practice certificate, and the Buddha's power of attorney above her head is compassion for all beings. The vow of the Bodhisattva Ksitigarbha is that hell is not empty and never becomes a Buddha. Only when all beings are exhausted can he prove Bodhi! Such a great oath year, long years, hard work, in the hot water, save all the suffering beings in Jambu-Di^pa! Guanyin Bodhisattva, closer to our earthly people, is as merciful as the inspiration of the vast number of salvation beings! In short, no matter which Buddha, the dharma is the same, without selfishness and with great compassion! According to the scene in your dream, it should be that your father wants you to know that he needs the power of western Buddhism to help him get rid of his suffering (believing in Buddhism, it is inevitable that people will kill when they are alive, and they will suffer some hell crimes when they go to hell)! You should burn more incense in the temple to enlighten your father, do more good deeds, release more animals, eat less meat and be vegetarian! Please read the Diamond Sutra or the Tibetan Sutra at home, at least once a day, and recite it for 7749 days. According to legend, the merits of reciting scriptures seven times can only be obtained by those who have been returned! Be a vegetarian before chanting, clean your hands, burn incense, and make a wish (usually in the scriptures)! Give all these merits back to your father and help him cross over!
How much hell has suffered! Read the Tibetan vows with love!
