One of the most important concepts in understanding classical Hinduism is the existence of a caste system. The caste system is a societal set up, in which people are born into a certain caste or group and they cannot change. Each of these groups is assigned a certain set of jobs. These jobs hold a certain level of importance in society. Some jobs are seen as important and others are viewed as being less important. These jobs also help to show a caste's level of power. The higher the caste, the more wealth and power in Indian society. The highest caste is the Brahmin, which consists of Hindu priests. Kshatriya is the 2nd most important caste, which is the warrior class. Viasya are landowners and merchants, and Sudra are commoners, peasants and servants. Outside the caste system are a group called untouchables. These people are the lowest group in society. They have few rights and the worst jobs in society, like rat catchers. The most common religion in India is Hinduism. Hinduism is a polytheistic religion, which means Hindus pray to more that one god. Hindus in different areas pray to different gods. The reason many Hindus pray to so many different gods is that Hinduism has no set doctrine, or written rules of practice. Though it does have some common characteristics no matter where it is followed. The belief in Dharma is the natural laws the world. These are rules every living creature must follow. Karma on the other hand is the result of ones actions in life. A person can control their own karma. Karma is the world's reactions to one's actions. If a person is kind and good in life, they will have good karma. If a person is bad or evil in life, they will have a worse time in their next life. If you are good you will have a good life, but if you are bad you will have a bad life. Ideas like Dharma and Karma are important concepts to Hinduism, but Hinduism is very open to many new beliefs. Hinduism is accepting of all beliefs. Hindus believe that the life they are living currently is not their only existence. After death there is not an afterlife, but only another life. This belief is called reincarnation Every living thing, from insects to humans, has a soul. When someone dies they are reborn as another creature. If a person is good in their life, their next life will be in a higher level of life. The highest level of life is called Moksha, in which a person is a spirit, similar to a god. Moshka are the only form above humans. If a person is bad in life, they are reborn as a lower creature. If a human is a bad person, they are reborn as an animal. They will have to wait several lifetimes for another chance to be a human. These reincarnations are seen as the reactions of the way a person lives their life, or their karma. Every human should try to have good karma and be reborn as a better being. The caste system serves as a way of separating humans. In the cast system people are separated into different groups, each group having different levels of power and jobs. The highest caste lives a very happy life, while the lowest castes must struggle to survive. This fact is very important, because it allows karma to be at work in humanity. Humans will be reborn into a higher caste if they live a good life. If a person does their job well and is a good member of their caste, they will be born into a higher caste in their next life. This is why a person cannot change castes in their lifetime, they must be reborn into the next caste. Buddhism is the religion of almost 400,000,000 people on earth, but it all started with the teachings of one man. Siddhartha Gautama was a Hindu prince born in Nepal in 563 BCE. He was a member of the Brahmin, or the highest caste in the Hindu caste system. Though he was very powerful and wealthy, he was still unhappy. He saw all of the suffering of his people. He did not know how to change it. When he was 29 he left home to find the meaning to life. He experienced many miracles and became very wise, the wisest human being ever. He traveled the world teaching his new philosophy. He came to be regarded as the Buddha. He was reborn several times to teach humans how to be enlightened, or to reach spiritual purity. Buddhism has many different teachings and themes, but one of the most important concepts is the Four Noble Truths. The Four Noble Truths help humanity to understand where suffering comes from. If a person knows where suffering comes from, they will be able to take suffering out of their lives. Buddhists believe that first people must understand that life is full of pain and suffering. This suffering is caused by human desire. If humans can put an end to desire, they can end suffering. Suffering can be ended by following a philosophy called the Eightfold Path. These truths are the first step to following the ways of Buddha and finding spiritual happiness. Spiritual happiness and purity, called enlightenment are the goals of Buddhism. Buddhists look to end personal suffering, and suffering in the world by following the Eightfold Path. Each one of the following 8 rules helps to lead a person to being a better person. A person should know that suffering is caused by desire, be selfless and love all life, not lie, not kill, steal or commit unjust acts, not do things to promote evil, take effort to promote righteousness, be aware of oneself and one's actions, and learn to meditate. If a person follows these rules, they will have less desire. Though these concepts seem easy to follow, they are not very specific. It can be very difficult to define just what "evil" is. Buddhists must think a lot about themselves and their actions to remain on the Eightfold Path. Though this takes a great deal of work and time, it can have a great deal of payoff in the next life. Buddha was a Hindu before he became the head of a religion. It should not be surprising that Buddhism is very similar to Hinduism. Buddhists believe in an endless cycle of reincarnation, which is similar to beliefs of Hinduism. Buddhists do not believe that gods are responsible for the phenomenon, like many Hindus do. In addition, the Caste System is rejected by Buddhists who believe instead that one is reincarnated until they can achieve nirvana, best described as spiritual enlightenment or purity. Buddhist beliefs point to a person's self is the source of happiness, while Hindus put more value on one's role in society. Buddhism has developed into its own distinct religion from Hinduism despite these similarities. It should be no surprise that religions that both started in South Asia have so much in common.
