Yes, although Love is the central theme of the plot, there are several minor plots in the book which makes the book even more interesting.
Soul mate is definitely one of them. People think a soul mate is your perfect fit, and that’s what everyone wants. But a true soul mate is a mirror, the person who shows you everything that is holding you back, the person who brings you to your own attention so you can change your life. A true soul mate is probably the most important person you’ll ever meet, because they tear down your walls and smack you awake. But to live with a soul mate forever? Nah. Too painful. Soul mates, they come into your life just to reveal another layer of yourself to you, and then leave. A soul mates purpose is to shake you up, tear apart your ego a little bit, show you your obstacles and addictions, break your heart open so new light can get in, make you so desperate and out of control that you have to transform your life, then introduce you to your spiritual master. To catalyst the above notion, the author has incorporated the essence of heroism into the plot. Heroes in fact die with one’s youth. They are pinned like butterflies to the setting board of early memories—the time when skies were always blue, the sun shone and the air was filled with the sounds and scents of grass being cut. I find myself still as desperate to read the Sussex score in the stop-press as ever I was; but I no longer worship heroes, beings for whom the ordinary scales of human values are inadequate. One learns that as one grows up, so do the gods grow down. It is in many ways a pity: for one had thought that heroes had no problems of their own. Now one knows different.
6 couples from different city, places & countries once again prove similar souls wander in the similar places! They may not know each other, but often they touch the same winds, they step on the same leaves, their looks are lost in the same horizons!
The author also gives a perspective of live while he concludes the plot. Life will break you. Nobody can protect you from that, and living alone won’t either, for solitude will also break you with its yearning. You have to love. You have to feel. It is the reason you are here on earth. You are here to risk your heart. You are here to be swallowed up. And when it happens that you are broken, or betrayed, or left, or hurt, or death brushes near, let yourself sit by an apple tree and listen to the apples falling all around you in heaps, wasting their sweetness. Tell yourself you tasted as many as you could.
