A ceremony known as Tulsi Vivah is performed by the Hindus between Prabodhini Ekadashi (eleventh lunar day of the waxing moon of Kartika) to Kartik Poornima (full moon in Kartika), usually on the eleventh or the twelfth lunar day. It is the ceremonial wedding of the Tulsi plant to Vishnu, in the form of his image, Shaligram or a Krishna or Rama image. Both the bride and the groom are ritually worshipped and then married as per traditional Hindu wedding rituals. It marks the end of the four-month Chaturmas period, which corresponds to the monsoon and is considered inauspicious for weddings and other rituals, so the day inaugurates the annual marriage season in India.
