Four-level initiation [proper terms of Tibetan Buddhism] The initiation of the Supreme Yoga Department of Tibetan Deformity is the second level, and its names are: bottle initiation, secret initiation, wisdom initiation and victory initiation. This is the second teaching method with the double-body method as the core. Its main theoretical basis is that the development of Qi pulse and lightness is the development of bodhicitta, so "becoming a Buddha" must be practiced through Qi pulse and lightness. The perfection of pulse training and light touch can only be accomplished by double-body (double-luck) method. The four top irrigation methods are as follows: (1) bottle top irrigation: short for bottle irrigation, also known as initial irrigation. This is a slow initiation to break the normal mind of disciples and give birth to a Buddha who is' I am a Buddha'. Its practice is to hold bottles, crowns, pestles, bells and other things for disciples to enlighten and confer dharma names. They are called Aquarius Restoration, Guan Bao Restoration, Mount Kumgang Restoration, Bell Restoration and Famous Restoration. These five kinds of initiation were taken at the beginning of initiation, representing the five parties and five buddhas respectively. After initiation, I realized that my disciples were cared for by the five buddhas, and they were able to show the slowness of the five buddhas in monasticism. After the initial irrigation, the main practice is concentration and visualization. (2) Secret venting: short for dense tail, also known as second irrigation. This is the beginning of practicing qi pulse and understanding. Its practice is to help develop disciples' spirit and insight through the guru's two-body method. After the second irrigation, I admit that my disciples are qualified to practice Bodhicitta (that is, to practice my own true qi, Ming Dian, Stupid Fire, Diamond Boxing, etc.). ). (3) Wisdom initiation: It is called wisdom initiation, also called triple infusion. This is the key point of the introduction of Tantric Supreme Yoga Department, and its content is the double body method. The practice is that the guru teaches his disciples to do the double body method under the premise of free adjustment, and protects the bright spot when practicing the qi pulse. Let the disciples prove that they are in a good mood. (4) enlightenment: it is the highest, last and most subtle recognition of the disciple by the guru. It was held in the final stage of the third irrigation practice, when disciples saw it with their own eyes and enjoyed wisdom and light. At this time, the guru explained to his disciples that the light of his victory in righteousness now is the light of Dharma Body revealed by Midvein. Therefore, the consciousness of winning righteousness is only the recognition of the realm, and there is no way to practice. Its purpose is to make disciples leave the cultivation of dirt while confirming the dharma body, and directly show their true respect for the Tathagata. After this enlightenment, the disciple has reached the point of no learning, completed the learning process and reached the realm of becoming a Buddha. Because the two-body law in these amendments, if implemented carelessly, is no different from sexual intercourse, and it is quite easy to breed the side effects of advocating lust. Therefore, Zong Kaba, the founder of Gelug Sect in Tibet, changed it into a visual princess (wisdom seal) instead of a physical princess. Even so, China's dominant religious Buddhism in the Han Dynasty did not agree with these practices. Therefore, some people denounced it as "left-handed secret riding", while others regarded it as the infiltration of Buddhism by Indian heretics. In any case, such a "double happiness for men and women" approach is very inconsistent with China's cultural character. Therefore, Buddhism did not prevail in China during the Han Dynasty.
