You might be knowing that there is partial solar eclipse on August 1st, 2008. Solar Eclipse has given a lot of importance in Hinduism. At the time of the eclipse, people are suggested to bathe in the sacred rivers. They should do charitable acts. They should donate cows, money and gold. One is suggested not not to take food during the eclipse. One should take food only after seeing the sun free from the eclipse. Pregnant women are advised not to see the eclipse otherwise the child born may have some kind of defect. Householders are forbidden from sexual intercourse on the day of the eclipse, for the same reason. Eclipse time is also considered very auspicious for sadhana (spiritual practice).
