Defining "Samsara"

Saṃsāra (संसार), a Sanskrit and Pāli term which translates as "continuous movement" or "continuous flowing" refers in Buddhism to the concept of a cycle of birth (jāti) and consequent decay and death (jarāmaraṇa, in which all beings in the universe participate and which can only be escaped through enlightenment. Saṃsāra is associated with suffering and is generally considered the antithesis of nirvāṇa or nibbāna

According to the Buddha, the beginning point of Saṃsāra is not evident. It is just like finding the beginning point of a circle. All beings have been suffering in Saṃsāra for an unimaginable period, and they continue to do so until attaining of nirvana

Saṃsāra is uncontrollably recurring rebirth, filled with suffering and problems (according to Kālacakra tantra as explained by Dr. A. Berzin). In this sense, Samsara may be translated "Wheel of Suffering."

The term Samsara has been translated many ways which include but are not limited to endless suffering, cyclic existence, perpetual wandering, and transmigration. There are six realms that one can go to through this cycle of Samsara. Many believe that when one goes through the process of rebirth that they are the exact same person when they are reborn. This however, is not true. They bear many similarities with their former selves but they are not the same person. This is why many use the term reborn instead of reincarnation. The term reincarnation implies that there is a transfer of conscience or one’s soul to the new life and this is not the case in Samsara.

buddha101.com gives a good example that shows an easy way to better understand the transfer of consciousness “Like a billiard ball hitting another billiard ball. While nothing physical transfers, the speed and direction of the second ball relate directly to the first." This means the previous life has just as much impact on the new life. There are also some who believe that Samsara is not the question but the answer to what we are doing here. They consider it to be a process to why we are here. They believe that one creates their own worlds on their way to enlightenment. Meaning when their world is starting to collapse due to their death they will create a new world and move into it. Some also believe that while they are continuing to go from world to world they encounter others who are on the same path that they are on. It is also believed that all of these different worlds impact the worlds of those who are in a similar place/path that you are on.

Buddha was the first person to grasp the belief of Samsara and figure out how to end it. He taught that the only way for one to end their journey through Samsara was enlightenment. The only person who could stop one’s cycle of Samsara was the one who was traveling through their path. Some thought that Samsara is a place and thought that it was selfish for them to be able to stop it and leave the others behind. Most believe that Samsara is a process. In this process people are being born into new lives and since it happens to everyone and everyone has the ability to escape it, it is not selfish. Being said the process of Samsara may take a long time to complete and even with no time limit there may be some who can never actually escape this endless suffering. (Wikipedia)
