Chiluku Dwadasi, also known as Ksheerabdi Dwadashi or Yogini Dwadasi, is the day dedicated to the worship of tulsi plant and observing the ritual of tulsi vivah. In 2012, Chiluku Dwadasi date is November 25.
This is celebrated on the dwadasi tithi of karthika masa and is very auspicious for worshipping Goddess Tulsi and Lord Vishnu.
During Chiluku Dwadasi, Lord Vishnu is worshipped in the form of a saligrama and devotees perform the tulsi vivah. Vishnu and tulsi are worshipped together and the saligrama is placed alongside the tulsi plant and the wedding is performed.
Tulsi is considered the incarnation of Maha Lakshmi on earth. It is a hindu tradition to worship Tulsi by offering water, little turmeric and kumkum and decorate it with flowers. Usually women in the house perform the tulsi puja everyday to get the blessings of MahaLakshmi.
On the day of Chiluku Dwadasi, devotees decorate the tulsi plant just like a bride and a branch of amla plant is kept alongside the tulsi plant for the worship. It is widely believed that Lord Vishnu visits the earth on the day and hence this festival is of utmost importance to the devotees. It is widely practiced by many communities around the country.
