Buddhism is considered one of the three most widespread and very important world religions. Buddhism was founded by the historical Buddha Gautama, in the 5th century BC. Buddhism began about 2,500 years ago by a young prince named Siddharthe Gautama. Living like a prince, he undertook religious activity trying to alleviate human suffering. Gautama earned the title Buddha meaning "The Enlightened One" when he found the answers to life's suffering. Buddhism revolves around the teachings of the Four Noble Truths and the Eightfold Path. The Buddha states that if these beliefs are followed, Buddhists will achieve enlightenment called nirvana, and thus be freed from the worries of the physical world. Siddhartha was the son of a king of a northern Indian kingdom. He lived a rich life and was destined to become a powerful king. At the age of 29 Siddhartha faced a sick man, an old man and a dead man. These meetings forced the young prince to reevaluate his spoiled life. He came to notice that wealth and luxury did not guarantee him happiness. He was determined to come to a deeper understanding of life, so he left the palace, leaving behind his father, his wife, and his son. He traveled for six years, studying with several yoga masters and spiritual teachers. He tried many forms of meditation and yoga, including severe fasting methods during which he nearly died. Once he found the Middle Way and achieved enlightenment, he began his quest to find the answer to the problem of human pain and suffering. The development of Buddhism was developed in stages. Starting from phase one; the historical Buddha who proposed the teachings and his students preserved the teachings. Phase two; this was the interpretation of the teachings, this... half of the paper... explain them. The first truth is that nothing is lost, matter is transformed into energy and energy is transformed into matter. If we destroy something around us, we destroy ourselves. If we deceive another, we deceive ourselves. Understanding this truth, the Buddha and his students never killed. The second universal truth is that everything is constantly changing. It's smooth in some places, but then it sticks out of nowhere. As soon as we think we are safe, something unexpected happens. The third universal truth explained by the Buddha is that there are constant changes due to the law of cause and effect. Buddhism is a very important way of life for those living in Southeast Asia. There may be some variation in power between women and men, but this does not surpass the power and beliefs of those who are followers of the Buddha. This is not just a religion; it is seen as a lifestyle.
