The Ascended Master Sanat Kumara has a very long history and he does not come from any particular (known) planet. He has described himself humorously as the “cosmic garbage collector” because he has traveled to several planets that were at the brink of self-destruction and has helped them enter an upward spiral. Sanat Kumara’s spiritual partner is the Ascended Master Venus.
Before coming to earth, Sanat Kumara worked on the planet Venus. A very long time ago, earth had descended to such a low level that cosmic councils were debating whether to allow the planet to self-destruct. Sanat Kumara then volunteered to come to work with earth and 144,000 lifestreams from Venus decided to follow him and embody on earth. Sanat Kumara created a spiritual retreat in the identity realm, and the lifestreams from Venus were magnetised there and created a physical mystery school in the area that is now the Gobi desert. You can read more about this in the book My Lives with Lucifer, Satan, Hitler and Jesus.
