Chandra Grahan, or the Lunar Eclipse, takes place gracefully when the Earth fiercely positions itself exactly between the Sun and the Moon, dramatically throwing a profound shadow across the lunar surface. Mirroring the deeply spiritual handling of solar eclipses, a lunar eclipse carries intense astrological weight in traditional Indian society. The luminous Moon deeply affects the human mind and global tides; thus, its sudden darkening represents a highly vulnerable period urging deep internalization.

History: Like the solar eclipse, the lunar eclipse explicitly involves the demon Rahu (and sometimes Ketu) aggressively seeking brutal revenge on the Moon God (Chandra) for assisting Lord Vishnu during the epic distribution of the cosmic immortal nectar.

Significance: The Sutak strictly begins 9 hours powerfully prior to a lunar eclipse. Pregnant women are intensely advised to remain prudently indoors to effectively shield the unborn child from harmful astrological rays. It heavily encourages immense spiritual chanting over chaotic worldly activities.
