Life pre-programmed?

My horoscope is beautifully written on palm leaves, carefully preserved by my loving parents for years. But I don't know if it has all good secrets of my future life, which I was always afraid of knowing in advance.

I had to go to an astrologer today as my mother wanted to start searching for a loving daughter-in-law (I mean a bride for me). Horoscope assured that I will be married by next year and my family is happy to know that as well. But my confusion starts here! How and Why every event in this world should happen a way it is pre-programmed? And I want to know where is that ultimate authority stays and operates from? I could not ask the astrologer anyway! But I could get a clue when I visited the neighbouring Shiva Temple in the evening. Today it was not just usual weekend visit to the temple, it was more than a normal relaxing and blissful moment for me at the temple. I was all alone standing infront of the temple thinking blank in the back of my mind. Let me see if I stand with a soul mate next year in the same place if it is destined to happen.
