The Ladder of Lights

Learn how you can deal constructively with the forces of darkness through a step-by-step technique to convert negative energies into positive spiritual light. This book contains an updated, practical version of the medieval ritual of Abra-Melin.

Polarities of Power

Between Good & Evil

George F. Pinder

Learn the fundamental concepts that underlie the physics of multiphase flow and transport in porous media with the information in Essentials of Multiphase Flow in Porous Media, which demonstrates the mathematical-physical ways to express and address multiphase flow problems. Find a logical, step-by-step introduction to everything from the simple concepts to the advanced equations useful for addressing real-world problems like infiltration, groundwater contamination, and movement of non-aqueous phase liquids. Discover and apply the governing equations for application to these and other problems in light of the physics that influence system behavior.

This textbook presents the timeless basic physical and mathematical principles and philosophy of environmental modeling to students who need to be taught how to think in a different way than they would for more narrowly-defined engineering or physics problems. Examples come from a range of hydrologic, atmospheric, and geophysical problems.

Introduction to Environmental Modeling

More and more Neo-Pagans are seeking to restore the matriarchal principle to their conceptions of divinity. This shows how it can be done, with rituals, evocations and discussion of our prime feminine deity. Gray's final book from his 20-title career.

Thermodynamically constrained averaging theory provides a consistent method for upscaling conservation and thermodynamic equations for application in the study of porous medium systems. The method provides dynamic equations for phases, interfaces, and common curves that are closely based on insights from the entropy inequality. All larger scale variables in the equations are explicitly defined in terms of their microscale precursors, facilitating the determination of important parameters and macroscale state equations based on microscale experimental and computational analysis. The method requires that all assumptions that lead to a particular equation form be explicitly indicated, a restriction which is useful in ascertaining the range of applicability of a model as well as potential sources of error and opportunities to improve the analysis.

Alan Richardson

As an "omniscient and obnoxious" teenager in 1969, Alan Richardson wrote to the occult author William G. Gray in pursuit of instant magical enlightenment. While he didn't quite get that, it was the beginning of a correspondence lasting many years in which Gray generously shared his magical knowledge and experience. Gray's letters, witty, ascerbic and blunt, contain a wealth of hints and tips on working and using Qabalah, his views on Dion Fortune, sex magic, initiation, joining magical groups, and how to stay on the straight and true path to Light regardless of what life flings at you. How does free-will relate to Destiny? Why do many great Adepts behave like idiots if they're in contact with Higher Powers? Is sex incompatible with a spiritual path? He addresses the questions which weigh on the mind of every magical seeker - always with the proviso that true wisdom can only be reached from within oneself. The letters are a delight to read and show the humour and understanding which shine through Gray's famously unsentimental character. They will be of direct practical value to anyone pursuing a magical path of any kind, Qabalistic or otherwise, and his advice to his young apprentice is every bit as pertinent today as it was back then.

Magical Ritual Methods

Inner Traditions of Magic

1965-1967 ... As the New Age seemed to explode into being, everything spiritual had to be Eastern. Psychedelic artwork showed Glastonbury Tor overshadowed by the Maharishi Mahesh Yogi, or Stonehenge sending its energies up to Lord Krishna - imagery which William G. Gray summed up quite simply as "Balls." He was working hard to make sure that our weakened (or slumbering) Western Traditions would survive. Among his endeavours at the time was this guide to the inner and outer practicalities of ritual magic, which includes instruction on god-forms, words of power, magic circles, initiation, extension of consciousness and raising power through ritual. Previously unpublished, Working with Inner Light is the first new book by William G. Gray since the author's death in 1992. Written in the form of a journal or magical diary, it includes his original sketches, and forms a detailed course in modern Qabalistic magic which will be of immense value to esoteric students and practitioners working within the Western Mysteries today.

Working with Inner Light

In the early 1970s the redoubtable old occultist William G. Gray bicycled from his Gloucestershire home to the Rollright stone circle in Oxfordshire on a clear and full-mooned summer night. The visionary experiences he encountered on that night and in other similar visits resulted in the writing of this book, originally published by Helios Books in 1975 and now a classic among pagan and craft traditions. The text of the ritual is given in full, along with a discussion of its pattern and purpose. The Rollright Ritual is a powerful initiatory rite for attuning oneself to a personal and communal path of spiritual growth, presented here with an explanatory text and a discussion of the spiritual lives and practices of the stone circle builders of Great Britain. "Somehow, we ought to get away from ideas that a Standing Stone is only an outworn sign of our past, and see it as an upraised Finger of Fate beckoning us ahead toward our future. The Stone is not merely a memorial of bygone beliefs, but a pointer that should raise our highest hopes of finding faith in all the Life that lies ahead of us."

This two-volume work constitutes the edited proceedings of the Tenth International Conference on Computational Methods in Water Resources (formerly Finite Elements in Water Resources), held at Heidelberg University, Germany in July 1994, organized jointly by Interdisziplinäres Zentrum für Wissenschaftliches Rechnen (Interdisciplinary Center for Scientific Computing) and Sonderforschungsbereich 359 of Heidelberg University and the Institute of Supercomputing and Applied Mathematics of IBM Heidelberg. The 1994 proceedings present the work of authors from 23 countries. Numerical methods, mathematical modeling and applications to subsurface and surface hydrology are covered by a wide variety of papers. Issues of formation description and modeling, including parameter estimation, heterogeneity, and scaling up continue to attract the attention of a large number of researchers. Several papers edited in this book concern the solution of the Navier--Stokes equations. For applied mathematicians, engineers and geoscientists working in the fields of numerical methods, hydrology, ecology, water resources planning and management, remediation design, porous media research, petroleum engineering and coastal engineering.
