Prabodhini Ekadashi signifies the awakening of the god. Chaturmas penance ends on this day. Many fairs that begin on Prabodhini Ekadashi end on Kartik Poornima, Kartik Poornima usually being the most important day of the fair.Fairs that conclude on this day include Prabodhini Ekadashi celebrations at Pandharpur and Pushkar Fair. Kartik Poornima is also the last day to perform Tulsi Vivah ceremony that can be performed from Prabodhini Ekadashi.
