Introduction
In the realm of celestial events, a Chandra Grahan, or Lunar Eclipse, is a truly fascinating phenomenon that has captivated cultures and civilizations for centuries. The word “Chandra” refers to the moon, while “Grahan” means eclipse in Hindi. This celestial event occurs when the Earth comes between the Sun and the Moon, casting its shadow on the lunar surface. As the Moon passes through the Earth’s shadow, it takes on a reddish hue, creating a breathtaking sight in the night sky.
Understanding Chandra Grahan
A Chandra Grahan takes place during the full moon phase when the Sun, Earth, and Moon are aligned in a straight line. There are three types of lunar eclipses: total, partial, and penumbral.
-
Total Lunar Eclipse: This occurs when the Earth completely blocks the Sun’s light from reaching the Moon. During a total lunar eclipse, the Moon can take on a vibrant red or copper color, often referred to as a “blood moon.”
-
Partial Lunar Eclipse: In a partial lunar eclipse, only a portion of the Moon enters the Earth’s shadow, resulting in a partial darkening of the lunar surface.
-
Penumbral Lunar Eclipse: This type of eclipse is more subtle, as the Moon passes through the outer part of the Earth’s shadow, known as the penumbra. It often results in a faint shading on the Moon’s surface.
Significance of Chandra Grahan
Across different cultures and traditions, lunar eclipses have been imbued with spiritual, mythological, and astrological significance. In Hindu mythology, a Chandra Grahan is believed to be caused by the demon Rahu devouring the Moon, only to have it released after a period of time. Rituals such as fasting, chanting of mantras, and taking a holy dip in sacred rivers are often observed during lunar eclipses to ward off any negative energies.
