The sixth day began with fasting and may have included a symbolic partaking of kykeon, a mixture of water, meal, and mint, which Demeter requested in place of wine when she had fasted in grief for her daughter. Sacrifices would also have been made.

Then, the initiates were brought into the enclosed part of the sanctuary, and from there, the workings of the cult of Demeter are forever hidden from history and from modern eyes. We do know that the Mysteries had three components: the Dromena (things enacted), the Legomena (things spoken), and the Deiknymena (things shown).

The Dromena was obviously a reenactment of some sort of the myths relating to Demeter and Persephone. Their exact nature, of course, is unknown. Speculation ranges from suggestions that the initiates reenacted searching for Persephone in the darkness to theories that the initiates were shocked with frightening images and ordeals to create the illusion of traveling through the underworld.

It is not known what exactly was spoken, but the Legomena were essential to the rites of the cult (and most likely explained them). Thus, all initiates were required to know Greek so that they could understand the Legomena. The culmination of the rites was the Deiknymena. The Hierophant, in a blaze of light in the door of the Anaktoron, would show the Hiera to the initiates. The nature of these items can only be guessed. However, the effect of these rites and the experience of seeing the Hiera are certainly not secret. The initiates were filled with joy and a sense of peace regarding the afterlife, and many regarded it as one of the most fulfilling and defining moments of their life.
