I found this belief system of foreign devotees to Sanatkumara : http://www.sanatkumara.info/traditions.htm
They have confused Karthikeya, the brother of Ganesha, son of Siva with Sanat Kumara, the son of Brahma, considered an avatar of Vishnu and and used a picture of Manikantha to boot!!! They claim the Hindu tradition!!!!
I wish they would correct themselves at least on the part that they ascribe to Hinduism.
