Question: In the prophecy of the Trees, it says Ksitigarbha Bodhisattva is both Melekh Shubkha and Ania, but another Manichaean document says that Shabala (Sabala) is also the same Bodhisattva. Are Melekh Shubkha, Ania, and Shabala one and the same? And what about Avalokiteshvara (Guan Yin in Chinese) the Call, or Karia? Is this Divinity associated with any other Aeons?
Shabala (Atlas) and Shubkha share the role of Ksitigarbha, so yes, they are the same, but only in the sense of sharing the responsibility of serving as such a Bodhisattva.
Avalokiteshvara is associated with various divine beings and Messengers. The name is used in a multitude of ways, much in the same way, for example, Amitabha Buddha. Amitabha is a name used for both Avalokiteshvara and for Buddha Moni. The name is also used in reference to the Living Spirit and a number of His various manifestations and emanations.
