First of all, from the aspect of faith revision, Hinayana Buddhism regards Sakyamuni as its leader, and thinks that there can only be one Buddha in the world, that is, Sakyamuni, but not two at the same time. Believers, through religious and moral cultivation such as "Eight Righteousness", can achieve Arhat Grosvenor (breaking the troubles of the Three Realms, transcending the cycle of life and death) and exorcising Buddha's fruit (realizing the Twelve Fates and Gaining the Tao), but they cannot become Buddhas. Mahayana Buddhism believes that there are countless buddhas in the ten parties of the Third World, and Sakyamuni is one of them. Believers can achieve Buddha's fruit (called "Bodhisattva", which means sentient beings with great awareness) by practicing the "six degrees" of Bodhisattva (giving, keeping precepts, enduring humiliation, diligence, meditation and wisdom), and expand the scope of becoming a Buddha. In addition, Mahayana Buddhism demands that one's own troubles should be eliminated immediately, and that one should pursue personal self-liberation, starting from life and death, taking greed and love as the root, and destroying one's body and mind as the ultimate goal. It is purely born, so Mahayana Buddhism derides him as "self-defeating". Mahayana Buddhism claims that Buddhism is merciful and merciful, and it aims at saving the world by becoming a Buddha and establishing a pure land of Buddhism. In his view, it takes countless lives and deaths to practice the certificate, aiming at "Maha Prajna" (great wisdom), and achieving "Atta Duoluo's three virtues and three bodhis" (supreme enlightenment). In addition to cutting off all his troubles, he should aim at saving all sentient beings. Therefore, since he was born, he also stressed that he should adapt to the world and open a generous door to extradite all beings.
Secondly, from the aspect of teaching theory and righteousness, the general tendency of Hinayana Buddhism is that "there is no law for me", that is, it only denies the reality of man and me, but not the reality of law for me. Mahayana Buddhism, on the other hand, not only advocates that man has no ego, but also thinks that law has no ego, that is, it denies the reality of law at the same time. The theoretical analysis of "Dharma without Self" in Mahayana Buddhism can be divided into two schools: one is the early Mahayana Buddhism (about the first century to the fifth century), and the middle school founded by Longshu and Tipo (called Mahayana Kongzong in China). It mainly expounds the theory of "nature is empty and false" in various laws, that is, it holds that all phenomena (laws) are caused by karma (various conditions), and they have no self-nature, so they are empty. But this kind of emptiness is not nothingness, and its false phenomenon still exists. The so-called false existence is based on Hinayana's theory that all laws are real in concept, that is to say, all laws are just a kind of "pseudonym". Long Shu and Tipo believe that the analysis of various laws with this theory is neither "real" nor "empty", which is the so-called "middle view". The second is Mahayana Buddhism in the middle period (from the 5th century to the 6th century A.D.), a school of yoga founded by Wuzhu and his relatives (known as Mahayana Sect in China). It mainly expounds the theory of "all laws are only knowledge", that is, it holds that all phenomena originate from "Arya knowledge" (also known as the eighth knowledge, hidden knowledge, etc.), and Arya knowledge can produce all laws. That is to say, they think that all laws exist in cognition, and cognition is nothing more than the separate function of mind and consciousness, so there is no entity in the whole universe except various kinds of cognition, so it is called "all laws only know". After the 7th century A.D., Indian Buddhism began to decline, and Tantric Buddhism (later Mahayana) took its place, which had no important significance.
In addition, Mahayana Buddhism has its own collection of classics as the basis for argument. The main classics of Hinayana Buddhism (in Chinese translation) are: Long agama, Han Jing in China, Zengyi agama, Za agama, etc. The main classics of Mahayana Buddhism are: Mahayana Sutra, Miraculous Lotus Sutra, Huayan Sutra, Nirvana Sutra, Great Wisdom Theory, Middle Theory (Made by Dragon Tree), Yoga Teacher's Land Theory (Made by Maitreya), Mahayana Theory (Not Made) and Mahayana Theory.
A famous Buddhist saying: If you don't achieve Buddha's fruit, you must have a good relationship first. If you throw a clear pearl into turbid water, the turbid water will have to be clear. If you put a Buddhist name into a confused heart, you will have to become a Buddha. If you don't know the truth, you will become a Buddha. If you can't do this, you can't do it. If you can't pay now, you can't do it. If you make all living beings happy, you will make everything happy.
