The six books of the Mahayana Yuan Yilin Chapters cite four meanings to clearly indicate the reasons for the establishment of the Three Jewels: (1) The Three Jewels of Evil against the Outer Path are the righteousness of opposing evil and returning to righteousness. (2) The Buddha is the master of the master, the Dharma is the Dharma of the other teacher, and the monk is the disciple of the other teacher. The evidence of these three is immeasurable, and the types are the same, so they form one law; but the cause and effect of the proof are different from each other, so they are divided into teachers and disciples. (3) The person with the upper root wants to obtain the evidence of the Buddha's bodhisattva, so he speaks of the Buddha's treasure; the person who has the middle root wants to seek natural wisdom and has attained the Dharma of karma, so he speaks of the Dharma Treasure; the person who has the lower root receives the Dharma according to the teacher, and the director does not violate it, so he speaks of the sangha treasure. (4) Buddhas are like good doctors, Dharma is like magic medicine, and monks are like caregivers; for a sick person, good doctors, magic medicines, and caregivers are indispensable.
In addition, in The Yogi Treatise Volume 64, it is mentioned that there are six meanings between the three Dharma monks: (1) The difference between the Buddha is the phase of natural enlightenment, the Dharma is the fruit of enlightenment, and the monk is the phase of the right practice that he teaches. (2) The difference between karma, the Buddha is the karma of converting to Orthodoxy, the Dharma is the karma of giving up the conditions of defilement and suffering, and the monk is the karma of courageous growth. (3) The difference between faith and understanding means that for the Buddha's treasure, there should be a letter and solution that is close to the undertaking; for the magic treasure, there should be a letter and solution that hopes to be verified; for the sangha treasure, there should be a letter and solution that lives with the contract and the Dharma. (4) The difference in practice means that for the Buddha's treasure, one should practice the right practice of offering and undertaking things; for the dharma treasure, one should practice the right practice of yoga convenience; for the monk's treasure, one should practice the right practice of receiving the dharma of wealth together. (5) The difference between following the thoughts should be said to be followed by the rest of the Buddha's treasure, the Dharma treasure, and the sangha's treasure. (6) The difference between the blessings of life is said to be the most victorious blessing born of the Buddha's treasure according to one sentient being, the most victorious blessing born of the Dharma treasure according to this law, and the most victorious blessing born of the buddha's treasure according to many sentient beings.
According to the theories, there are many types of the Three Jewels, and there are usually three kinds of differences, namely: (1) the Three Treasures of the Other Phase, also known as the Three Treasures of the Ladder and the Three Treasures of the Other Body. That is to say, the Buddha, the Dharma, and the monks are different, and the Buddha first became enlightened under the Bodhi tree, but when he showed the body of the sixth buddha, and when he said the Huayan Sutra, he was especially presented as the body of the Lushena Buddha, so it was called the Buddha Treasure. The Mahayana, Hinayana and other sutras that the Buddha spoke of at the fifth hour are called Dharma Treasures. In the teachings of the Buddha, the sound of the sound of cause and effect, the enlightenment, the bodhisattva, etc., are called the sangha treasures. (2) The Three Treasures of One Body, also known as the Three Treasures of homogeneity and the Three Treasures of Homogeneity. In terms of its meaning and essence, the Three Jewels of Buddha, Dharma, and Sangha have three names, but their physical nature is one. For example, from the standpoint of the enlightened person, the Buddha is called the Buddha Treasure for the sake of the spiritual consciousness of the sexual body, according to the Dharma, non-emptiness and non-existence, so it is called the Buddha Treasure; but the Buddha virtue is enough to follow everything, that is, the Dharma nature is extinguished, and the Hengsha Nature Virtue can be maintained, so it is also called the Dharma Treasure; and if the Buddha is a state of harmony and harmony, the characteristics of the Sangha are harmony and no slander, so it is also called the Sangha Treasure. In this way, one Buddha treasure is enough to possess three treasures. (3) The Three Jewels of the Abbot refer to the Three Jewels that have been passed down and maintained in future generations, namely the Three Jewels of Buddha statues, sutra scrolls, and monastic monks. Mahayana believes that the eight-phase enlightenment path is the abbot Buddha, all the teachings of the Yishi are the abbot's dharma, and the three mahayana who have been enlightened and established are the abbot monks, and these three are called the three treasures of the abbot.
The above are the three kinds of three treasures, in addition to the four kinds of three treasures (one body three treasures, three treasures of karma, three treasures of incarnation, three treasures of abbot), six kinds of three treasures (homology, other body, one multiplication, three multiplication, truth, abbot) and so on. The Three Jewels are the source of the world's freedom from suffering, so there is the act of returning to the Three Jewels, called the Three Returns, also known as the Three Returns, which is the first element of buddhism.
