Thelema is a philosophical, mystical, and cultural system that is based upon a seemingly simple premise: do what thou wilt. This phrase, called the Law of Thelema, is not to be interpreted as a license to indulge in whim, but rather as a mandate to discover and fulfill one's essential nature or path in life, which is called True Will (those who are dedicated to this path are called Thelemites). This Will is the expression of one's deepest, most genuine self which acts in perfect accord with the Universe.
Modern Thelema began in 1904 with the writing of a short text, titled The Book of the Law (which is often abbreviated as Liber Legis, Liber AL, or simply AL), by the British author, mystic, and poet, Aleister Crowley. This small book was to form the foundation of a complex system designed to promote True Will in both individuals and culture as a whole. The practical system of Thelema, which Crowley termed Magick, was eventually to draw from many existing religions, philosophies, and spiritual practices, most especially Western medieval occultism, Eastern Yoga, and the Hebrew Kabbalah (especially the Tree of Life).
Although much is written about it, Thelema has no precise definition, leaving it largely up to the individual to interpret. It is, however, possible to identify common principles that are generally accepted within the larger Thelemic community. These are by no means definitive nor exhaustive, but do provide a basic framework within which to develop a beginning understanding of Thelema.
True Will must be discovered
Crowley, like most spiritual teachers, recognized that one's Will is generally buried beneath a thick layer of what can be called Individual Ego—the conscious sense of "I" that feels separate from the Universe and is a complex mix of beliefs, values, and norms derived from socialization and various life experiences. A Thelemite is therefore one who seeks to break through her "conscious programming" in order to reconnect with the secret self, thereby becoming aware of her true, unfiltered nature. This process is called the Great Work.
The techniques used to accomplish this difficult task fall under the general term Magick, and traditionally include practices such as yoga, invocational ritual, and astral body work. In more recent years, Thelemites have been starting to include other, non-"occult" methods to accomplish the Great Work, such as transpersonal psychotherapy, hypnosis, and isolation tanks. In the end, it is up to the individual to find the doorway to her own inner self.
Human Divinity
Thelema utterly rejects the notion of original sin, and states, rather, that we are all divine creatures—“Every man and every woman is a star” (AL I:5). As such, Thelema rejects the idea that emotional states like guilt, shame, and pity are virtues, and instead recognizes positive virtues, such as honor, pride, and courage. Thelema also does not recognize any personified source of "evil", such as the Judeo-Christian Satan (although a personification named Choronzon is used to represent malicious confusion, egotism, and illusion). Rather, Thelemites are encouraged to discover their own divinity, as well as their personal sense of right and wrong, based on both rational thinking and through apprehension of their True Will.
Love & Sacred Sexuality
Thelema—which is Greek for Will—is paired with Agape, the Greek word for Love. Love, from a mystical point of view, is the drive to achieve Union, thereby losing the sense of ego-individuality and isolation. This theme is repeated again and again within Thelema, and is considered to be the key to accomplishing the Great Work. This is reflected in the core expression of Thelema from The Book of the Law:
Do what thou wilt shall be the whole of the Law. (AL I:40)
Love is the law, love under will. (AL I:57)
This notion of divine Love is personified in the Thelemic deities Nuit and Hadit, who represent (respectively) the Union of the infinitely-expanded Goddess of the Night Sky and the infinitely-condensed masculine Point, the hidden Flame in the being of all that lives. Their Union results in the birth of Ra-Hoor-Khuit (or Horus), the Hawk-Headed sun god, called the Crowned and Conquering Child.
As such, Thelema recognizes that the fundamental nature of the Universe is creative, which is reflected and embodied in the act of sex. As such, consensual lovemaking is considered to be a sacrament, and can even be used for personal devotional or transformational rites. By extension, the absolute freedom for all consenting adults to engage in sex as they Will is an important cultural element within Thelema.
Aeons
Thelema divides history into Aeons, which are large blocks of time (about 2000 years) that embody specific spiritual concepts. The first was the Aeon of Isis, with a focus on the Maternal Goddess and Mother Earth. After that was the Aeon of Osiris, representative of the paternal Dying God, which reflected the notions of self-sacrifice, original sin, and guilt. The current Aeon, which is marked as beginning in 1904, is that of Horus. The Aeon of Horus is that of the Child, the sovereign individual, who seeks his own unique identity and path of self-actualization, free from shame and fulfilled in Light and Joy.
Balance
Crowley is quoted as saying, "Equilibrium is the basis of the Work" (Liber Librae). As such, achieving balance is a key element within Thelema, in terms of both the worldly and the spiritual. This includes balancing pride with humility, light with dark, matter with spirit, knowledge with wisdom, logic with emotion, and even free will with destiny. It is through the reconciliation of apparent opposites that Attainment is possible. Perhaps the finest summary of Thelemic equilibrium is the phrase, "Act passionately; think rationally; be Thyself."
Thoughtfulness and the rejection of blind faith
Thelema inspires free thinking, skepticism, and the scientific-method over blind faith, which Crowley defined as "acceptance of any statement as true without criticism, examination, verification, or any other method of test." Thelemites very rarely believe something "just because."
This is why Thelema is often thought of as a Gnostic religion. Gnosis is Greek for "knowledge," and as as such, Thelemites are expected to accept beliefs only through the process of direct experience and substantiation. A Thelemite does not want to have faith in God...she wants to know God (and eventually come to realize that she IS God).
Independence and Liberty
Although most Thelemites recognize that humans are intrinsically interdependent, Thelema requires that one aspire to self-reliance and a sense of personal responsibility for one's own actions and well-being. Also, Thelemites tend to be suspicious of authority, often choosing their own unique paths. As such, deeply embedded within Thelema is the value of Liberty—to make one's own choices about major life issues, such as career, sexual partners, and creative expression. Very importantly, Thelemites strive to avoid interfering in anyone else's process of discovering and expressing their own Will, recognizing that this only leads to confusion and disharmony.
Thelemites promulgate the Law, but do not convert
Practices such as proselytizing and conversion are strongly discouraged within Thelema, since Thelemites hold that interpretation of The Book of the Law is a task strictly for the individual. At the same time, many undertake the duty of promulgating the general principles of Liber Legis (as outlined above), thereby spreading the Law of Liberty. The object is to inspire others to acknowledge their own unique Will and then to attempt to discover and express it.
