Cycle of life and death.

Edit:. I typed in my shot from the hip recollection of Samsara. I wasn't aware of the fact that there were many versions/interpretations of Samsara.
I'm familiar with the Buddhist version.

(https://en.m.wikipedia.org/wiki/Saṃsāra)

Saṃsāra in Buddhism, states Jeff Wilson, is the "suffering-laden cycle of life, death, and rebirth, without beginning or end".[109] Also referred to as the wheel of existence (Bhavacakra), it is often mentioned in Buddhist texts with the term punarbhava (rebirth, re-becoming); the liberation from this cycle of existence, Nirvana, is the foundation and the most important purpose of Buddhism.
