An Energy Sharing Ceremony was a ritual that was used by the Taelons where they shared their Core energy. Whilst strictly used by the Taelon race, some Humans were able to participate in the Ceremony by altering their bodies to match a Taelon's energy levels. Such a process allowed them to physically and spiritually bond with the Taelons.

Zo'or participated in this Ceremony on Earth with a unique group of women known as The Cloister. However, unknown to anyone except Da'an, Zo'or had undergone the Ka'ath'am that was the reproductive cycle amongst the Taelons. (Episode: Cloister)
