This Saturday is Pandava Nirjala Ekadasi, an auspicious day within the Vaisnava calendar where we Vaisnavas fast from everything, including water, from sunrise to sunrise.  I'm often asked about Ekadasi, especially Pandava Nirjala Ekadasi, so the following is a short outline for those who don't know.  This will be quite long so do be patient.

This is an excerpt describing the phenomena of Ekadasi from the Padma Purana, "Kriya-sagara-sara".
