A solar eclipse occurs when the moon passes between the sun and Earth, blocking the sun's light, and is often associated with various cultural superstitions. Many cultures believe that eclipses can bring misfortune, particularly for pregnant women, leading to practices such as staying indoors and throwing away food. Lunar eclipses are caused by the earth's shadow on the moon, and they also have their own set of beliefs and rituals, including bathing in holy rivers to cleanse oneself of evil spirits.
