The Diamond Approach is a path of personal awakening to the true nature of reality. The Ridhwan School is the unique inner work school founded and guided by A.H. Almaas.

The Ridhwan School is a loosely-knit affiliation of ongoing groups, which has been unfolding over the last 30 years and now has members in many parts of North America, Europe and Australia. Hameed Ali (A.H. Almaas) is the spiritual head of the School, while individual groups are taught by qualified Ridhwan teachers.

The Diamond Approach is the spiritual teaching, the path, and the method of the Ridhwan School. The Ridhwan Foundation is the nonprofit spiritual organization established to support and preserve the integrity of the Diamond Approach teaching. Its educational branch is the Diamond Heart and Training Institute (DHAT), which is responsible for making the teaching available to the public; for training teacher/ministers; and for supporting the publication of teaching material through books and audiovisuals.

Minister/teachers offer the Diamond Approach teaching through various formats including individual guidance sessions, public workshops, and ongoing groups. Only ordained Ridhwan minister/teachers are authorized to teach the Diamond Approach.

Theosophy is a body of ideas which holds that all religions are attempts by man to ascertain "the Divine," and as such each religion has a portion of the truth. Theosophy, as a coherent system of thought, developed from the writings of Helena Petrovna Blavatsky (also Hélène). Together with Henry Steel Olcott, William Quan Judge, and others she founded the Theosophical Society in 1875.

A more formal definition from the Concise Oxford Dictionary describes Theosophy as "any of various philosophies professing to achieve a knowledge of God by spiritual ecstasy, direct intuition, or special individual relations, esp. a modern movement following Hindu and Buddhist teachings and seeking universal brotherhood." Christian Theosophy is a branch that strives for the knowledge of God and Jesus obtained by the direct intuition of the Divine essence.

Adherents of Theosophy maintain that it is a "body of truth" that forms the basis of all religions. Theosophy, they claim, represents a modern face of Sanatana Dharma, "the Eternal Truth," as the proper religion.

The five prominent symbols visible in the seal of the Theosophical Society are the Star of David, the Ankh, the Swastika, the Ouroboros, and above the seal is the Aum. Around the seal are written the words: There is no religion higher than truth.

Energy healing can be seen as applied mystical spirituality.

Kundalini is the energy seen by Hindu mystics to be involved with enlightenment. They observe that enlightened people have free flowing Kundalini.

Aikido: The name aikido is formed of three Japanese characters, ???, usually romanised as ai, ki and do. These are often translated as meaning union, universal energy and way, so aikido can be translated as 'the way to union with universal energy'. Another common interpretation of the characters is harmony, spirit and way, so Aikido can also mean 'the way of spiritual harmony'. Both interpretations draw attention to the fact that aikido's techniques are designed to control an attacker by controlling and redirecting their energy instead of blocking it. An analogy is often made of the way a flexible willow bends with the storm, whereas the stout oak will break if the wind blows too hard. (The Korean martial art commonly known as hapkido uses the same three characters: some suggest a historical link through Daito-ryu, the main origin of aikido).

Shamanism refers to traditional spiritual practices practiced for millenia.
