The lambada is the traditional Easter candle that everyone in Greece holds on the evening of “Megalo Savvato” (Holy Saturday). It is believed that the "holy" light arrives from Jerusalem in every church a little before midnight, thus allowing candles to be lit!
At midnight the resurrection of Christ is announced, the priest then says "Χριστός Ανέστη" ("Christos Anesti", Christ is risen) and the believers answer "Αληθώς Ανέστη" ("Alithos Anesti", in truth he is risen). At the same time, fireworks and firecrackers are fired. When the faithful return home, they draw a cross with the holy light on top of their door.
