The Supreme Buddha saw the endless journey of birth and death of all beings. It is remarkable how insightful the way he taught us about the reincarnation. He saw the way we are trapped within this journey without even knowing it. He described about this situation in his whole life, so that we can get at least some idea about how dangerous this journey is. Buddha taught us that if there is someone who is born in this world today, then that person should have been born somewhere prior to this life. If he could not realize Dhamma in this life, then he will definitely be born somewhere again. This is a brief introduction on the truth that the Gautama Buddha realized about the birth and the death.

After the death of a person, the five matters of attachments (Pancha Upadanskandha) correspond to that birth detached from its current body or location and conceive at another place. That is how one dies and be born as another person in somewhere.

There is no other person who saw the existence of birth and death (the Sansara) like the Supreme Buddha. The Great One saw each and everyone’s births as animals like pigs, chickens, snakes, dogs, and so on and so forth. He also revealed the existence of low-level (Niraya, Preta, Asura) and high-level (deity) worlds, and how the beings are born in those worlds. Accordingly, not everyone is reborn as humans after their deaths.

The nature of our deeds (Karma), whether it is good or bad, will decide the characteristics of our next life.

Karma is not permanent. Therefore, we can change it if we act based on what Buddha showed us. Then, we will also be able to free ourselves from being a victim of Karma.

It is inaccurate to consider reincarnation as a false aspect. The Punarbhavaya or the reincarnation is not a false aspect. It is a truth, and there is a way to confirm this truth by practicing Buddhism. We need to practice meditation and attain the fourth state of concentration (Dhyana) in which the meditator will have the ability to check upon his past lives. Then, you will be able to see your past lives and confirm the reincarnation.

Whether there are scientists who believe in reincarnation or not, it (Punarbhavaya) is still true. We cannot categorize scientists as the greatest of wise persons of all time. Their knowledge changes from time to time and it is based on the results they perceive with their general senses (the eye, ear, nose, etc…) after performing an experiment. Some scientists believe the reincarnation, while some do not. The important thing is to think wisely and become a person who believes it. If we can look into our past lives by developing our minds, then what is the need of a scientist to verify the reincarnation for us?

Not all the humans are born again as humans after their deaths. Likewise, there is also a possibility for the beings of other worlds to get births as humans. There are billions of beings in low-level worlds such as animal world and hell. Even if a small portion of these beings are reborn as humans, then that portion could be larger than the current population of humans in the entire world. This is why we see it as a population increment in overall.
