Parikrama is a spiritual walk undertaken by the devotees, circling the village of Vrindavan (Krishna's Playground). This path covers a distance of 10 km (6 miles)and will take about three hours. It is generally done on Ekadasi (eleventh lunar day of the waxing and waning of the Moon). During the Parikrama, one chants the mantras (Japa or Hymns ) within, uses bodily strength (Tapasya) to accomplish the Parikrama and should fast (Vrata) until the Parikrama is completed.
