The length of the initiatory process varies between Candomblé houses but usually lasts from a few weeks to a few months. The initiate is first brought to the terreiro, where they are left for a period of relaxation, the "descanso", so that they might become 'cool', as opposed to 'hot'. They will be dressed in white clothing; a small bell may be attached to them to alert others if they leave the terreiro. One of the first acts during the initiatory process is to give the initiate a string of beads associated with their orixá. The necklace is colored according to the tutelary orixá of the initiate; white for Oxalá, dark blue for Ogum, or red and white for Xangô, for instance. These beads will be washed and sprinkled with the blood of a sacrificed animal. These beads are sometimes perceived as protecting the wearer from harm.
