You must have read many biographies and auto-biographies of the successful people in the genre of personal success literature by people in different walks of life; one such book by Napoleon Hill, Think and Grow Rich has been read by many millions. Many books like Deepak Chopra's The Seven Spiritual Laws of Success have been quite popular with the readers.
The point here is: how many people have actually benefited from these books? While we may or may not have the statistical data to prove or disprove them, but we can use astrology as a tool to see whether we have any chance of becoming successful in our lifetime.
Ascendant is most important house in any horoscope. If the native has any chances of being successful, it is this house that has to be strong; for, without the power of ascendant and its lord the chances of the native enjoying success do not exist. Ascendant and its lord both make the foundation of success. Ascendant is both a trine and angular house in a horoscope; therefore, if its lord has a connection with one of its kind then the native's fortune would be in ascendance. For a person of Cancer ascendant a combination of Moon and Mars can be wonderful. Here, the Moon is the lord of the ascendant and Mars is the lord of the fifth (Scorpio) and the tenth (Aries) house. Aries is the day house of Mars, while the tenth house is mid heaven itself; this house also shows southern direction, Mars has full directional strength in the south. Aries is also the Mool-Trikona house that is only next to exaltation house in importance for Mars. For the Cancer ascendant Mars is a totally auspicious planet as, on account of its ownership of the tenth house, it loses its evil nature and on account of its ownership of fifth and trinal house it becomes totally auspicious.
An exchange of Mars with the Sun, the lord of the second house of accumulated wealth can do wonders for the native. Here the Sun will be in its exaltation with full directional strength. If such a Mars is joined by the Moon and/or Jupiter; or if Jupiter is in the Ascendant, in Cancer, its exaltation, such a native will be equivalent to an all-powerful king. Venus in Taurus in the eleventh will be like icing on the cake. A combination of Mars and Jupiter in the fifth Scorpio and Moon in the eleventh-Taurus, its exaltation-or in the ascendant can also be a marvelous ruling and wealth giving combination for such a native. Similarly, presence of Jupiter and Moon in ascendant can produce a great person.
