Humans are always interested in foreknowing their future. There are many different predictive methods followed among the various human populations . When a particular method prediction goes correct for us we tend to believe in that.
I am sure that human intelligence has developed some such methods to a more or less practical proximity with a reasonable margin of error. I consider astrology as one of them. However as astrology has a vast number of parameters and they become innumerable by the various possible permutations and combinations, there can be some errors in the resultant predictions because of human error or insufficient experience and knowledge.
The same situation happens in the case of many other areas including health sector. Many diagnoses go wrong, many times the issue never gets diagnosed correctly etc. Many times general solutions do not apply for all and some customised solutions have to be applied.
It is well understood now how moon influence occurrence of tides and how the human mental system also gets affected by Moon. The life on Earth is powered by the energy from Sun, Mon and also from stars. Astrology takes the celestial factors like Sun, Moon ,and other planetary bodies and their inter positional relationship. We can infer that our ancestors have done lot of work and found how these bodies and their inter-positions affect human life. As we do not have the records of those research and imperative data, we may not be ready to accept them. So at present the belief in astrology comes only after you have some experience of predictions coming true.
I started having some faith on astrology only after a few astrological predictions regarding my life turning true. The predictions were recorded and available even before I reached that stage. Moreover, when I made a cross check with another astrologer far away from me and who have never heard or sen me, he also gave the same predictions.
Now my stand is that yes, astrology has its strong base. But as it is a very elaborate segment, not all are equipped with the full needed knowledge. That is why many times the predictions go wrong and make us skeptic about astrology.
However, believe me, eventhough I say astrology is a knowledge source for predictions and understanding our life, I do not read the daily predictions coming in the magazines or TV. I have not consulted an astrologer except the indirect one which I narrated earlier. The only other occasion I visited a astrologer was in relation to matching horoscopes for the marriage of my sister -a few decades ago.
