Dr. Clark L. Wilkerson DD. was a born January 24th, 1919.
He was a student and teacher of metaphysics, student of Hermetic science and Yoga. Twelve years a Rosicrucian, associate of the Great White Brotherhood, psychic and clairvoyant.
Student in Hawaii of Huna science from the kahunas.
Ordained Reverend.

Author of Hawaiian Magic, highly recommended book. (It is strong in areas of removing fixations and mental complexes. Not pure huna, also includes laws of the universe, and channeled information.) His other books, from which Hawaiian Magic draws mightily, were Know Thyself Subcionsciously, Celestral Wisdom, Cosmic Wisdom Attunement, Private Consultations of a Kahuna. He also authored Wisdom from Venus.

He started out being the head Kahuna on Oahu, then sold out his inheritance, and moved first to Pacific Pallisades in California, then later to Las Vegas.

Dr. Wilkerson founded the Institute of Cosmic Wisdom in 1965, together with his soul mate, Dr. Dei Wilkerson.

He passed away.

His wife Dei Wilkerson renewed copyrights on his/their books in 1997.

Recently, the Hawaiian Magic book became available for some short time in e-book format (Adobe Acrobat PDF), and the vendor (Huna-ohana.com) claimed to have approval from heirs of Dr. Wilkerson (if I remember correctly).

An institution exists called Church Of Cosmic Wisdom, which was confirmed to be related to Clark Wilkerson by a student of him.
They have an exempt status as of March 1974 and their contact address is:
CHURCH OF COSMIC WISDOM
220 KAALAWAI PL
HONOLULU, HI

The Church Of Cosmic Wisdom was never open to the public. The members of The Church Of Cosmic Wisdom were Clark Wilkerson himself and the Huna priests and Priestess'es that were personally ordained by himself.
