(1) Early Buddhism opposed the caste system advocated by Brahmanism, the theory that God created four castes, and denied the privileges of Brahmanism scriptures and Brahmanism monks. Early Buddhism tried to break the strict boundaries between castes in the religious field and put forward the slogan of "equality of all beings" It advocates that anyone can enter religion and get rid of pain through practice. There is no hierarchical discrimination in Buddhism. Although this slogan is mainly based on the interests of Kashatri nobles and upper-class monks and demands equality with Brahmins, it also reflects the desire of the general public to oppose Brahmanism and demand caste equality.
(2) The main doctrine of early Buddhism is the theory of "four truths". "True" means "true". "Four truths" are four truths. These four truths are bitter truths, gathering truths, destroying truths and Tao truths.
The bitter truth is that everything in life is bitter. Buddhism believes that there are eight major hardships in life, namely, birth, old age, illness, death, love and parting, resentment and hatred, ambition, five yin filling (that is, five yin filling bitterness, yin filling "accumulation", collection meaning. "Five Yin" refers to all physical and mental sufferings in life. Five yin and five aggregates refer to color, acceptance, thinking, behavior and knowledge. These five troubles are blazing and are caused by the accumulation of these five aggregates. All beings can't get rid of the mystery, and they can't get rid of the desert sea.
Collecting the truth is the reason why life is so bitter. Buddhism believes that the tragic root of life lies in all kinds of "love desires" (that is, the desire for love), including the desire for pleasure, longevity and power. If there is a desire for love, there will be action, and if there is action, there will be "karma" (the consequences of action). People will constantly change jobs and suffer from various hardships such as birth, aging, illness and death.
(3) Eliminating truth refers to eliminating suffering. Buddhism believes that to eliminate pain, we must eliminate the root of pain-the desire for love. If you want to destroy love, don't make a career. If you don't create karma, there will be no reincarnation. When samsara is eliminated, we will be liberated and enter the highest ideal of Buddhism-"Nirvana". The free translation of "Nirvana" is extinction; Death; Not born. That is, eternal silence. It is the immortal fantasy of Buddhism. Beyond the highest realm of reincarnation forever, there is no such realm, it is just a pseudonym of death.
(4) Tao is the way to explain nirvana or the method of cultivation. Buddhism believes that to achieve "nirvana", we must do things according to the five precepts and the eight right paths. The five precepts are: abstain from killing, stealing, debauchery, lying and drinking. The right path is: a "right view", that is, a correct belief, putting aside all false views and facing up to the "four truths." Second, "mindfulness" means thinking about "four truths" and thinking correctly. Three "positive words", that is, correct remarks, don't say all unreasonable words. Fourth, "proper business", that is, correct behavior, should keep a clean body and start a career; Five "righteous life", that is, a correct life, living according to the canon and living a proper life; Sixth, "positive progress", that is, making correct efforts, should make continuous progress and cultivate the way of Boston; Seven "mindfulness", that is, mindfulness, not moving evil thoughts, remembering the right path; Eight "positive definite", that is, correct self-concentration, focusing on a situation, meditation is not chaotic.
