Shri Ranganathan, While on the subject of astrology, one rule which, again, I learned informally from a very experienced person, is that if the 9th. and 10th. houses are linked in any one of the many possible ways, the native will surely prosper and go to a higher position in life compared to the one in which he/she was born. The bhava chart is to be taken and I feel - no proof, but - BVR's bhava calculation system is the best. I have found this to be a rule which rarely fails, but, depending on other details the rise of the native will be through fair or unfair means. In case you have many horoscopes, you may like to test and let us know if this works.
