I Believe In Reincarnation

Since Buddhism is my religion, I strongly believe that there is a thing called “Reincarnation”.
Reincarnation definition: “Reincarnation best describes the concept where the soul or spirit, after the death of the body, is believed to return to live in a new human body, or, in some traditions, either as a human being, animal or plant.”
The reason why people forget their past life is because that during his reborn he had suffered alot within the uterus of his mother's body. When the mother do a ultrasonic test, we can see this fetus is really painful, the head and the feet is upside down and the fetus has to hanging like this for about ten months!
If the mother moves, the fetus will feel like if there is an earthquake; if the mother drink cold water, the fetus will feel like as they are on ice; if the mother drink hot water, the fetus then would feel like as they are in a hot pot. It's like a prison for them. Even though they will eventually get out, it is still painful. When the baby gets born, he has to go through two “huge mountains”, they squeeze his body, and once they got out, they started to cry, this is because the uterus is soft and smooth, once the baby feel the air, it's like needles sticking through them. Of course they are gonna try, have you ever see any baby get born with a smile on their face? Because of this pain and this torture, the person or the soul had forgot all his memories, so most of people has no memory of their past lives, and this makes sense.
Here is a real example of reincarnation: “A Boy's Experience of Living Two Lives in Hainan Province. An article on the seventh issue of the magazine Oriental Women in 2002
reported a story of a boy who remembered his previous life. The boy was called Tang Jiangshan. He lived in Gancheng Town of Dongfang City, Hainan Province. According to Tang Jiangshan's parents and old villagers, when Tang Jiangshan was only three years old (in the year of1979), one day he suddenly told his parents, "I am not your child, II was called Chen Mingdao in my previous life and my dad in that life was called Sandie. My home was in Danzhou, where it was close to the sea."The place he mentioned was more than 160 kilometers away from Dongfang City. The boy also mentioned that he was killed by sword and gun duringthe Cultural Revolution. What was stranger was that he could speak the Danzhou dialect very fluently. The Danzhou dialect was completely different from the dialect in his hometown in this life of his. There were also some scars made by swords on his waist left from his previous life.
At 6, Tang Jiangshan kept urging his parents to take him to where he lived in his previous life: Huangyu Village, Xinying Town of DanzhouCity. Tang Jiangshan walked straight towards the house of an old man called Chen Zanying. Tang Jiangshan called Chen Zanying "Sandie" in Danzhou dialect. He told Chen that he was Chen's son called Chen Mingdao. After he died, he was reincarnated in Gancheng Town of Dongfang City. He came back for his parents from his previous life. Then he recognized his two older sisters, two younger sisters and other relatives in that village. What was especially interesting is that he could also recognize his girlfriend in his previous life. Even though Tang Jiangshan was only 6 years old, what he talked about from his experiences in the previous life convinced Chen Mingdao's families and relatives that Tang Jiangshan was Chen Mingdao in his previous life. Chen Zanying was so moved on the spot and cried with Tang Jiangshan. Chan believed that Tang Jiangshan was reincarnation of his own son Chen
Mingdao. Since then, Tang Jiangshan has had two families, parents from two families. Every year, he traveled between Dongfang city and Danzhou. Chen Zanying, his relatives and villagers all regarded Tang Jiangshan as Chen Mingdao. Since Chen Zanying didn't have a son, Tang Jiangshan took care of him as his son until Chen Zhanying died in 1998. Editors working for the magazine didn't believe Tang Jiangshan's story in the beginning. But after careful investigation, they eventually verified the reliability of Tang's experience.”

There are still many examples out there and they had been proofed by many people. I believe there is reincarnation and it leads to many human fundamental rules. First, if you want to born in a good family your next life, you have to be a good person while in this life. Second, don't ever get abortion, this soul within your body will hate you forever and you will live in this guilt forever. Third, believe in some kind of religion, but there are different kinds, choose wisely because evil religious would ruin your life and let you regret forever.
