A deceased person's body is not embalmed; rather, it is ritually washed by members of a group called the chevra kadisha (literally 'holy society'), who then dress the body in a simple linen garment (tachrich), place it in a simple wooden casket (no metal, so that the body's return to dust is hastened), and stay with the deceased while reciting psalms. At the funeral, there is no viewing. Eulogies may be given, and mourners may recite psalms (especially Psalm 23, 'The Lord is my shepherd; I shall not want) and El Malei Rachamim ('God, full of mercy'). Cremation is forbidden, and burial should take place as soon as possible. At the burial, mourners take turns shoveling dirt into the grave, but do not pass the shovel directly to one another. A common myth states that having a tattoo prevents one from being buried in a Jewish cemetery; though Judaism discourages tattoos, that is not true. Proper treatment of the dead is considered a critical mitzvah (both commandment and good deed) because the beneficiary (the deceased person) cannot offer repayment or express gratitude.
