Why is samsara important?

Answer 1

Let me quote from the Complete Works of Swami Vivekananda (pp. 53-54, 207-208) to answer this question: "Samskara can be translated very nearly by 'inherent tendency.' Using the simile of a lake for the mind, every ripple, every wave that rises in the mind, when it subsides, does not die out entirely, but leaves a mark and a future possibility of that wave coming out again. This mark, with the possibility of the wave reappearing, is what is called Samskara....When a large number of these samskaras are left on the mind, they coalesce and become a habit. It is said, "Habit is second nature", it is first nature also, and the whole nature of man; everything that we are is the result of habit. That gives us consolation, because if it is only habit, we can make and unmake it at any time. The Samskaras are left by these vibrations passing out of our mind, each one of them leaving its result. Our character is the sum-total of these marks, and according as some particular wave prevails one takes that tone. If good prevails, one becomes good; if wickedness, one becomes wicked; if joyfulness, one becomes happy. The only remedy for bad habits is counter habits; all the bad habits that have left their impressions are to be controlled by good habits. Go on doing good, thinking holy thoughts continuously; that is the only way to suppress base impressions. Never say any man is hopeless, because he only represents a character, a bundle of habits, which can be checked by new and better ones. Character is repeated habits, and repeated habits alone can reform character."
