Seems like it was Gargamoney, according to this letter.
If you write to him he may give you the details.
My Dear Gargamuni,
Please accept my blessings. After a long time, I beg to thank you for
your letter dated 31, January, 1969 from the Spiritual Sky store. You
have given a very nice name. At least you are giving ideas to the
people in general that there is a Spiritual Sky, and they will get
information sufficiently about Spiritual Sky, the planets thereof, the
inhabitants of these planets, etc., through the medium of your store,
the Spiritual Sky.
