Do you realize that in ancient times, astrologers were beheaded for not alerting the emperor in advance about eclipses. Eclipses were taken as negative omens. It's true, they're not the greatest days for important new beginnings or advancing one's material affairs. On the other hand, there is really no need to make eclipses into dreaded events. In fact, eclipses are wonderful for introspection, meditation, cleaning house, letting go of old baggage, quiet time or any other spiritual pursuit. The idea of paying attention to eclipses, or any astrological event for that matter, is simply to harmonize your action with the astrological weather.
Eclipses can be used on different levels as well. The most common way to use an eclipse in astrology is as an omen or sign portending global trends or events. Typically, because the eclipse is caused by a shadow passing across the Sun or the Moon, it is taken as an indication of negative events, suggesting problems for particular countries, leaders, or some aspect of world politics. On the other hand, eclipses can also be used for individuals. The astrological house in which the eclipse takes place will usually become sensitized for up to 6 months. If the eclipse falls near the same degree as a planet in the person's natal chart then it affects that planet and everything it symbolizes in the chart. If the eclipse falls on the person's natal Sun, Moon, Ascendant, or ruler of the Ascendant, then it will have a powerful effect.
In the course of the ordinary activities of day to day life, eclipses should be avoided for important new beginnings in material areas. If you are thinking about starting a business, getting married, approaching your boss for a promotion, or proposing to your girlfriend, then an eclipse is not the time to do it. On the other hand, if you are thinking about going camping, going on a retreat, starting psychotherapy, ending a relationship, quitting a job, cleaning house, or just spending some quiet time, then an eclipse can be a good time to start.
In the decision making process eclipses come in handy as well. If, for example, you find your dream house, or someone makes you a job offer at the time of an eclipse, it is generally a good idea to leave it. Things which you are presented with at this time are usually either short-lived or develop unforeseen problems later.
If the thing that you are deciding or starting is of an introspective or spiritual nature, however, then the eclipse might indicate a positive outcome. This is because eclipses tend to negate the material and give to the spiritual aspect of life. For this reason, in the Mantra Yoga Samhita, a classical text on the practice of mantras, it is said "If there is an occasion of an eclipse even in a condemned month, then the initiation (starting of a mantra) becomes auspicious. There can be no better time in the world for initiation than an occasion of a Solar Eclipse."
The Nakshatra in which an eclipse falls will also give a clue to its effect on both nations and individuals. Generally, the nakshatra and whatever it symbolizes will be spoiled for the next six months after the eclipse. For this reason various remedial measures have been prescribed by the ancient Vedic Rishis in order to counteract the effect of an eclipse in each nakshatra. In India, it is common for people to fast for 10 hours before an eclipse and then perform a havan (fire ritual) in the middle of the eclipse. In the west, where Vedic pundits are more scarce, the recommended activity during an eclipse is meditation, or possibly the chanting of an appropriate mantra for the Nakshatra in which the eclipse is occurring.
