Vultures of Tibet, the best in the “Life and Death” shorts showcase, is a gorgeous study of the Tibetan sky burial, a tradition that calls for dead bodies to be left exposed to the elements. Vultures flock to pick flesh from bone, emphasizing a tenet of Buddhist faith—the body is temporary and the soul is forever. (The Chinese tourists who swarm to gawk at the tradition, meanwhile, deserve a fate no better than an insect’s in their next lives.) The appeal of the sky burial is its all-encompassing approach to life and death. Its functional purpose is paired with a calming faith in the inevitable: “We can’t choose where we are born or deny we will die.”
