New Age and esoteric literature often mention Ashtar Sheran, who allegedly is a higher dimensional being, or Ascneded Master, who is the administrative head of the Ashtar Command.
According to some he is energetically connected to Venus.
Sometimes he is referred to as 'Commander,' which does not seem to be a hierarchical term, but more of a way of expressing respect for him.
Because of his connection to Venus, and his position in the Ashtar Command, there are a lot of similarities to Sanat Kumara.
Lots of channels claim to be channeling Ashtar Sheran.
