Tulsi Pujan Diwas, observed on December 25th, falls on an auspicious Thursday this year, honoring the sacred Tulsi plant. Worshipped for purity and devotion, the day offers an opportunity to seek blessings from Tulsi Mata and Lord Vishnu for peace and prosperity. Devotees can observe rituals like early morning bath, wearing yellow, and circumambulating the Tusli plant today.
