user65: Every Buddhism believe in Eternity or Samsara. So, how can I imagine of Samsara?. What is the starting of it ?
 Any suggestions would be really appreciated.

user145: Beginning of Samsara is stated by Buddha as not knowable for ordinary beings. Knowing rightly would be to not imagine in regard of its beginning.
Usually Samsara is imagined as round of re-births in the six realms, or much more detailed view as bhavacakra.

user7141: Your question has two parts so i will answer in the following order...
How to understand "Samsara" and how it works.
Sansara or Samsara is the word Lord Buddha picked to name a certain circle of death and life.
What is samsara
As we Buddhists believe as long as a being lust for existence he will be born according to his Karma.To this process we call "Sansara or Samsara".
So where is the start of samsara? 
Even Lord Buddha was intrigued by the question and started to find a solution.The only way to do it is to look back into your own past to find your first life.So Lord Buddha went back countless amount of lives and understood that the "Beginning" is very ancient the time we have in a life is not enough to look back and see that life.So lord Buddha said this to the Sangha  "There is no point in looking for a start,it is too old and trying to find an answer is a waste of time".And advised that no one should try to find an answer to it (Because they will not be able to find it)
So my friend that question can't be answered by any being in the universe,Because if there is something out of Lord Buddha's reach it is out of anyone's reach.
So how does samsara work?
How it works is complicated but i will give you a simplified version of it.
Samsara needs fuel like your car,As long as you give fuel to it it will keep working and you will have life after life to live.
Let me give an example from lord Buddha....
"Karma is the paddy field,Lusting is the water,vinyana is the seed"
In the real world without water a seed will not grow,likewise without "Greed or lust" you will not be born,without it there is no samsara but as long as you have it you will have samsara and you will have to suffer in whatever karma brings you.

user471: The beginning of samsara is inconstruable and not evident, yes, but it definitely happened when the mind-body phenomena emerged out of ignorance and started craving and clinging.

As he was sitting there he said to the Blessed One: "'A being,' lord.
'A being,' it's said. To what extent is one said to be 'a being'?"
"Any desire, passion, delight, or craving for form, Radha: when one is
caught up there, tied up there, one is said to be 'a being.'
"Any desire, passion, delight, or craving for feeling... perception...
fabrications...
"Any desire, passion, delight, or craving for consciousness, Radha:
when one is caught up there, tied up there, one is said to be 'a
being.'

user-1: The answer to your question depends on how one understands the word "start." Etymologically, the English word means to jump, leap up, or move or spring suddenly, thus, to arise, to come into being. In accordance with the law of karma, the whole process of samsara itself must be self-starting. 
This can be proved logically based on the law of karma, which requires that every cause have an effect and every effect a cause. Since samsara is time itself, the essence of time is the identity of cause and effect, thus, the moment, which is then extended in space as past and future to create the infinitely differentiated  world that we experience. 
However, as the illusory negation of reality samsara must inhere in the non-illusory, which is reality itself. Therefore, samsara also inheres in reality, and in that sense has a logical - but not a temporal - "origin." This "start" is the principle of karma itself, which is the inherent kinetic principle in transdual reality. 
This is necessary to explain our experience of samsara. Otherwise, there would just be nothing at all. This point of identity of samsara and reality is, once again, the moment. Therefore, the answer to your question is that the start of samsara is the inherently timeless and therefore eternal moment, which paradoxically is the origin of time, space, and causality that endlessly differentiates in infinitely variegated patterns. This view of the cosmos remarkably presages certain theories in modern physics, especially the holographic theory of the universe.

user111: Is there a starting point to a circle? Just like that, there's no starting life to Sansara. But you can break this circle at 2 points. 

Ignorance.
Craving.

That is when you attain Nibbana.

user172: According to the suttas, samsara has no beginning. There are many references to this.
