Varaali,
Thank you for finding my post from last week and responding.
This is the Sanat Kumara I am referring to. In this information, it says that this Sanath Kumara was actually the son of Krishna, being Pradyumna. It also references him to Skanda/Kartikkeya.
Sanat Kumara appears as a rishi in the Hindu religious text the Chandogya Upanishad. A shrine to Sanat Kumara which attracts and unites people of all religions and faiths is situated in the town of Katargama, Sir Lanka. In Sanskrit, "Sanat Kumara" is "Eternal Youth" (from Sanat "eternal", and Kumara] a "youth").
The Kumar resides in the most sublime center of our planet, Shamballa, the sahasrara of the world. The Kumara has several names, relating to the sahasrara centers of different Systemic Existences: At the Supra-Cosmic plane, he is called Sanatana; at the Cosmic plane, it is Subrahmanya; at the Solar plane, the Kumara is Sanaka; at the Planetary plane, it is Sanandana; and on this planet, it is Sanath Kumara. So Sanath Kumara is an aspect of Kumara that resides in Shamballa.
Scriptures, especially the Mahabharata, say that it is Sanath Kumara who comes down to help the Divine Plan of Creation, when Lord Krishna came to be. He was born to Lord Krishna as his son, and he was named Pradyumna. Sanath Kumara incarnates himself through the Divine Mother Rukmini as Pradyumna. On completion of his work, He again gets back to his original position and takes to the seat in Shambala as Sanath Kumara. These details are given in the last chapters of Mahabharata. Sanath Kumara is the Planetary Lord. It is said that He receives the energies from higher planes, in the month of Aries, and transmits them to the Spiritual Hierarchy in the month of Taurus.
Sanat Kumara is regarded as the great guru, saviour of Earth. Believers in him see him in all the major religions, as Skanda/Kartikkeya in Hinduism, Brahma-Sanam Kumar in Buddhism, the Ancient of Days in Judeo-Christian traditions, and identify him as Ahura Mazda in Zoroastrianisn. (It is also considered that Sanat Kumara is Al Khdir (green man) known to Sufi Muslims (according to Dakshinamurti.
