In Sanatan Dharma, the Tulsi (holy basil) plant holds great spiritual importance and is considered highly auspicious. It is believed that Goddess Lakshmi resides in Tulsi, and daily worship of the plant brings her blessings. Beyond its religious significance, Tulsi is also revered in Ayurveda for its numerous medicinal benefits.Devotees usually offer water to the Tulsi plant and perform its circumambulation (parikrama) as part of their daily rituals. Doing so is said to attract prosperity and divine grace. However, according to scriptures, Tulsi should not be watered on Sundays, as it is considered inauspicious. Here’s the religious reasoning behind this belief.Why Tulsi Should Not Be Watered on SundaysWhile watering Tulsi daily is seen as highly auspicious, scriptures advise against offering water on Sundays. According to ancient beliefs, on Sundays, Tulsi observes a “Nirjala Vrat” (a fast without water) in devotion to Lord Vishnu. Offering water to the plant on this day is believed to break her vow, which is considered disrespectful.Astrologically, it is also said that watering Tulsi on a Sunday can attract negative energies into the home, disrupting peace and prosperity.Days When Tulsi Leaves Should Not Be PluckedApart from Sundays, Tulsi leaves should not be plucked on Ekadashi, Dwadashi, during solar or lunar eclipses, or after sunset. It is believed that on these days, Tulsi observes a waterless fast for Lord Vishnu, and disturbing her is considered inauspicious.Disclaimer: The content provided here is based on beliefs and information only.
