This collection of 18 lectures delivered in Paris, France by Rudolf Steiner in 1906 is a must for any serious student of Steiner's philosophy. Ranging from esoteric insights into Christianity and Yoga, to astral planes and apocalypses.

Of all of his works, The Philosophy of Spiritual Activity is the one that Steiner himself believed would have the longest life, and the greatest spiritual and cultural consequences. It was written as a phenomenological account of the results of observing the human soul, according to the methods of natural science.

Based on brief, pithy quotations from Rudolf Steiner's collected works, the "spiritual perspectives" in this volume present core concepts on the subject of epidemics. These brief extracts do not claim to provide exhaustive treatment of the subject, but open up approaches to the complexity of Steiner's extraordinary world of ideas. Some listeners will find these fragments sufficient stimulus in themselves, whilst others will use the source references as signposts toward deeper study and understanding.

Hermeticism or Hermetism is a philosophical system based on the purported teachings of Hermes Trismegistus (a legendary Hellenistic combination of the Greek god Hermes and the Egyptian god Thoth). These teachings are contained in the various writings attributed to Hermes (the Hermetica), which were produced over a period spanning many centuries (c. 300 BCE — 1200 CE) and may be very different in content and scope.

Only he who understands life will be able to take his lessons from life itself. He will draw up no capricious schemes, for he knows that no other fundamental laws of life will prevail in the future than such as prevail in the present. Theosophy will therefore of necessity have respect for the existing state of things. Even, should it still find in what is existent, very much that might be improved, yet it will not fail to perceive in the present the germs of the future. But it knows, too, that for all things nascent there is a growth and a development.

Astral projection is a term used in esotericism to describe an intentional out-of-body experience that assumes the existence of a soul called an "astral body" that is separate from the physical body and capable of traveling outside it throughout the universe. Here is the definitive classical Theosophical audiobook on a subject which has enthralled humankind since near the beginning of time.

Where PiHKAL focuses on a class of compounds called phenethylamines, TiHKAL is written about a family of psychoactive drugs known as tryptamines with TiHKAL being an acronym for Tryptamines I Have Known and Loved”. Like its predecessor, this book is divided into two parts. The first part of the book begins with the story of Alice and Shura, a fictionalized autobiography, which picks up where the similar section of PiHKAL left off. The book opens with the story about the DEA raid that occurred a few years after the publication of their first book, PiHKAL.

When Rudolf Steiner gave these lectures 80 years ago, industrial farming was on the rise and organic methods were being replaced in the name of science, efficiency, and technology. With the widespread alarm over the quality of food in recent years, and the growth of the organic movement and its mainstream acceptance, perceptions are changing. The qualitative aspect of food is once again on the agenda, and in this context Rudolf Steiner's only course of lectures on agriculture is critical to the current debate.

At the beginning of his career, Joseph Campbell developed a lasting fascination with the cultures of the Far East, and explorations of Buddhist and Hindu philosophy later became recurring motifs in his vast body of work. However, Campbell had to wait until middle age to visit the lands that inspired him so deeply. In 1954, he took a sabbatical from his teaching position and embarked on a year-long voyage through India, Thailand, Cambodia, Burma, Hong Kong, Taiwan, and finally Japan.

Countless would-be readers and listeners of Finnegans Wake - James Joyce's 1939 masterwork, on which he labored for a third of his life - have given up after a few pages and "dismissed the book as a perverse triumph of the unintelligible." In 1944, a young professor of mythology and literature named Joseph Campbell, working with novelist and poet Henry Morton Robinson, wrote the first guide to understanding the fascinating world of Finnegans Wake.

Writing as Magus Incognito William Walker Atkinson explores the Seven Aphorism of the Rosicrucian doctrine. These traditions emphasize the pursuit of spiritual enlightenment and personal transformation through the understanding of hidden truths and the transmutation of the self. He describes the path of the Rosicrucian initiate: a journey of self-discovery, spiritual development, and the attainment of higher states of consciousness.

The interaction between mankind and spiritual beings—of Divine Encounters—as recorded in scriptures and ancient texts provides a powerful drama that spans Heaven and Earth, involving worship and devotion, eternity and mortality, love and sex, jealousy and murder. But how much of these are based on real happenings and how much is based on myth? With a visionary's ardor and a scientist's attention to detail, Zecharia Sitchin, author of The Earth Chronicles, gives a stunning account of human interaction with celestial travelers

Knowledge of the Higher Worlds and Its Attainment or How to Know the Higher Worlds is Steiner’s most essential guide to the modern path of initiation he advocated throughout his life. It has been translated into many languages and has inspired hundreds of thousands around the world. With great clarity and warmth, Rudolf Steiner details the exercises and moral qualities to be cultivated on the path to a conscious experience of supersensible realities.

Alexander (better known as “Sasha”) and Ann Shulgin’s PiHKAL: A Chemical Love Story has become a foundational work in the genre and was the first book to fully impart the how-to chemistry, and convey the effects, of many of the entheogenic drugs that are currently being studied and used to heal trauma and deal with death.

During the fall and winter of 1901–02, Steiner gave a series of lectures called “Christianity as Mystical Fact” to members of the Theosophical Society. The lectures were rewritten and issued as a book later that year. They mark a watershed in the development of Western esotericism.
