Homa Variations

"Throughout human history, and in many religious cultures, offerings are made into fire--known in the tantric world as homa. This collection provides detailed studies of the homa from its inception up to the present, allowing for the study of ritual change over long periods of time, and across religious cultures"--

Throughout human history, and across many religious cultures, offerings are made into fire. The essays collected in 'Homa Variations' provide detailed studies of this practice, known in the tantric world as the 'homa, ' from its inception up to the present.

Evaluating the aromaticity of a molecular system and the influence of this concept on its properties is a crucial step in the development of novel aromatic systems. Modern computational methods can provide researchers with a high level of insight into such aromaticity, but identifying the most appropriate method for assessing a specific system can prove difficult. Aromaticity: Modern Computational Methods and Applications reviews the latest state-of-the-art computational methods in this field and discusses their applicability for evaluating the aromaticity of a system. In addition to covering aromaticity for typical organic molecules, this volume also explores systems possessing transition metals in their structures, macrocycles and even transition structures. The influence of the aromaticity on the properties of these species (including the structure, magnetic properties and reactivity) is highlighted, along with potential applications in fields including materials science and medicinal chemistry. Finally, the controversial and fuzzy nature of aromaticity as a concept is discussed, providing the basis for an updated and more comprehensive definition of this concept. Drawing on the knowledge of an international team of experts, Aromaticity: Modern Computational Methods and Applications is a unique guide for anyone researching, studying or applying principles of aromaticity in their work, from computational and organic chemists to pharmaceutical and materials scientists. Reviews a range of computational methods to assess the aromatic nature of different compounds, helping readers select the most useful tool for the system they are studying Presents a complete guide to the key concepts and fundamental principles of aromaticity Provides guidance on identifying which variables should be modified to tune the properties of an aromatic system for different potential applications

Jainism originated in India and shares some features with Buddhism and Hinduism, but it is a distinct tradition with its own key texts, art, rituals, beliefs, and history. One important way it has often been distinguished from Buddhism and Hinduism is through the highly contested category of Tantra: Jainism, unlike the others, does not contain a tantric path to liberation. But in Making a Mantra, historian of religions Ellen Gough refines and challenges our understanding of Tantra by looking at the development over two millennia of a Jain incantation, or mantra, that evolved from an auspicious invocation in a second-century text into a key component of mendicant initiations and meditations that continue to this day. Typically, Jainism is characterized as a celibate, ascetic path to liberation in which one destroys karma through austerities, while the tantric path to liberation is characterized as embracing the pleasures of the material world, requiring the ritual use of mantras to destroy karma. Gough, however, argues that asceticism and Tantra should not be viewed in opposition to one another. She does so by showing that Jains perform “tantric” rituals of initiation and meditation on mantras and maṇḍalas. Jainism includes kinds of tantric practices, Gough provocatively argues, because tantric practices are a logical extension of the ascetic path to liberation.

Advances in the Theory of Quantum Systems in Chemistry and Physics is a collection of 32 selected papers from the scientific contributions presented at the 15th International Workshop on Quantum Systems in Chemistry and Physics (QSCP-XV), held at Magdalene College, Cambridge, UK, from August 31st to September 5th, 2010. This volume discusses the state of the art, new trends, and the future of methods in molecular quantum mechanics and their applications to a wide range of problems in chemistry, physics, and biology. The breadth and depth of the scientific topics discussed during QSCP-XV are gathered in seven sections: I. Fundamental Theory; II. Model Atoms; III. Atoms and Molecules with Exponential-Type Orbitals; IV. Density-Oriented Methods; V. Dynamics and Quantum Monte-Carlo Methodology; VI. Structure and Reactivity; VII. Complex Systems, Solids, Biophysics. Advances in the Theory of Quantum Systems in Chemistry and Physics is written for research students and professionals in Quantum systems of chemistry and physics. It also constitutes and invaluable guide for those wishing to familiarize themselves with research perspectives in the domain of quantum systems for thematic conversion or simply to gain insight into the methodological developments and applications to physics chemistry and biology that have actually become feasible by the end of 2010.

“Here there be dragons”—this notation was often made on ancient maps to indicate the edges of the known world and what lay beyond. Heroes who ventured there were only as great as the beasts they encountered. This encyclopedia contains more than 2,200 monsters of myth and folklore, who both made life difficult for humans and fought by their side. Entries describe the appearance, behavior, and cultural origin of mythic creatures well-known and obscure, collected from traditions around the world.

The tantric Buddhist traditions emerged in India beginning in the seventh century CE and flourished there until the demise of Buddhism in India circa the fifteenth century. These traditions were disseminated to Central, East, and Southeast Asia, and continue to be practiced, most notably in Nepal, Tibet and Japan, as well as in the numerous Tibetan traditions disseminated around the world by Tibetan masters living in diaspora. The central scriptures for these traditions were generally designated by the term tantra. Tantras are works that purport to relate secret teachings of the buddhas that enable awakening in as short as one lifetime. As such they are understood by their advocates to be the inspired speech of a buddha, and hence worthy of inclusion in the canons of Buddhist traditions. Over the past twenty years there has been considerable growth in the study of tantras as well as translations of these works into Western languages. This volume provides a detailed introduction to the Buddhist tantras. It addresses their development in India, their dissemination to Central, East and Southeast Asia, and their reception in these contexts. It introduces the key teachings in the tantras, as well as the history of their interpretation, and their connection to traditions of ritual, and contemplative practices. It also introduces the classification of the tantras and their place in Buddhist scriptural canons. It concludes with a look at the transgressive rhetoric that characterizes many of the tantras, the impact this had on their dissemination and translation, and the ways in which Buddhists explained this. It suggests that transgressive rhetoric and practices served an important role in Buddhist tantric traditions, which may be why they persist despite the challenges they have presented to the dissemination of these traditions.

Scholars of Vedic religion have long recognized the centrality of ritual categories to Indian thought. There have been few successful attempts, however, to bring the same systematic rigor of Vedic Scholarship to bear on later "Hindu" ritual. Excavating the deep history of a prominent ritual category in "classical" Hindu texts, Geslani traces the emergence of a class of rituals known as santi, or appeasement. This ritual, intended to counteract ominous omens, developed from the intersection of the fourth Veda - the oft-neglected Atharvaveda - and the emergent tradition of astral science (Jyotisastra) sometime in the early first millennium, CE. Its development would come to have far-reaching consequences on the ideal ritual life of the king in early-medieval Brahmanical society. The mantric transformations involved in the history of santi led to the emergence of a politicized ritual culture that could encompass both traditional Vedic and newer Hindu performers and practices. From astrological appeasement to gift-giving, coronation, and image worship, Rites of the God-King chronicles the multiple lives and afterlives of a single ritual mode, unveiling the always-inventive work of the priesthood to imagine and enrich royal power. Along the way, Geslani reveals the surprising role of astrologers in Hindu history, elaborates conceptions of sin and misfortune, and forges new connections between medieval texts and modern practices. In a work that details ritual forms that were dispersed widely across Asia, he concludes with a reflection on the nature of orthopraxy, ritual change, and the problem of presence in the Hindu tradition.
