What does Samsara mean to Buddhists? How is it meaningful?

The Buddhist way to see the Samsara, or the circle of life and death, is, according to my understanding: **Innumerable causes and effects.** Is this right? Is there a special *meaning* conferred by this, to the practitioners of Buddhism? What does it mean to Buddhists? In comparison, in my opinion, Hinduism delivers more *meaning* to its practitioners, with regards to Samsara, as seen in this Bhagavad Gita quote: **BG 7.14: My divine energy Maya, consisting of the three modes of nature, is very difficult to overcome. But those who surrender unto Me cross over it easily.** It gives a *meaning*. The existence is reflecting a super-consciousness, which is not unreal or trivial, it is a super-consciousness that reflects our actions, our feelings, our nature which create obstacles and mirror all craving for material world as the way routing far from the beginning point, the point inside a circle, the center, indeed. I cannot perceive a reality that I should refuse for the nature of emptiness while I am living in this very reality, without at least a *meaning* of what it is. After all, If it has no meaning, why would Gautama Buddha appear in this world, then disappear without saving all people inside the Samsara itself? Isn't this a contradiction? I would like to discuss the above peacefully. This is not a provocation. I'm sure Buddhism has a logical explanation for this and I would like to hear it from this forum.
