The existence of Buddha is positive, but details about the accident of his life and his essence of Dharma or doctrine often range from scripture to text. The contradiction in the details of Buddha's story is the result of several clauses about his life and doctrine and the fact that they were recorded in about 400 years after his death. Every text still contains consistent information, and text does not always send information in the same way.
According to the biography of Buddha, he is Mahupurusha (great existence) named Shvetaketu. Tushita Heaven is the name of the kingdom where he lived on Earth before he lived as Gautama Buddha. The Buddha has not been born again. Before leaving Tusita Kingdom and being born on the earth, I appointed Maitreya to replace that position. Maitreya will not return to him again, but will come to Earth as the next Buddha. Krishna is the past life of Saruptra, the main disciple of Buddha. In Krishna's life, he did not gain enlightenment. Therefore, he regained his reincarnation in the life of Buddha and entered the first stage of enlightenment after encountering an understanding Buddhist disciple. After being appointed to Buddha Sangha, he reached full Arahantship or woke up perfectly
Traditional Gautama biography usually contains many miracles, signs, and supernatural events. In these traditional biographies, the personality of Buddha is completely transcended (Skt.lokottara) without being influenced by the secular world, and it is perfect existence. In Mahāvastu, in the lives of many people, Gautama does not need to sleep, despite this "world adaptability", painless birth without sexual intercourse, does not include food, medicine, or bathing and Ability to "suppress karma". However, some of the more general details of his life come from these traditional sources. In modern times, people try to form a secular understanding of Siddhartha's life by omitting the traditional supernatural elements of his earlier biographies.
