This book, “The Buddhivilasini: Commentary of Ganesa Daivajna on the Lilavati of Bhäskaracarya II” is a version of the thesis, for which Dr V. Ramakalyani has been awarded the degree of Doctor of Philosophy by the University of Madras in 2018. Among the published commentaries on Lilavati, Buddhivilasini stands out for its characteristic treatment of the original work as Buddhivilasini contains more than hundred upapattis (Indian proofs) for almost all the rules of Lilavati. In the context of Buddhivilasini, upapatti is either a description of the process, numerical demonstration thereof, verbal explanation, reasoning utilising algebraic rules, proportion, examples or justification. This book consists of nine chapters. First chapter introduces the background relating to Indian contribution to mathematics. Second to eighth chapters consist of study of the upapattis on parikarmastakam (eight operations on arithmetic, fractions and zero), prakirnakas (miscellaneous units), misra-vyavahara (investigation of mixed units) sredha-vyavahara (progressions), Ksetra-vyavahara (geometry), Itara-vyavahara dealing with the khata (volume of excavations), citi (stacks), rasi (mound of grains) and chaya (shadows and gnomon), kuttaka (an indeterminate equation of degree one) and ankapasa, dealing with combinatorics. The translation of the passages in Buddhivilasini and explanations in modern notations are given with valuable remarks. Ganesa’s contribution to mathematics, style of commenting and his erudition are discussed in the last chapter. Six appendices, bibliography and index are given at the end. On the whole this is a valuable contribution to the historiography of mathematical literature in Sanskrit.
This book deals with the various aspects of science and scientific thoughts of the Vedic bards reflected in their hymns. Attemps have been made here to analyse the Vedic verses in scientific terms adhering to various branches of modern science.
This book Vedic Science and Technology contains, in its ten chapters, the significant aspects of science and scientific thoughts of the Vedic bards reflected in their hymns and the modern scientific theories developed later. The Vedic deities symbolize the natural phenomena which the human beings of that period came across in their day-to-day life and had interactions with such events. Ostensibly, the modern scientific theories and practices have their roots in the most ancient tradition and culture. Various branches of knowledge such as Astronomy, Astrology, Cosmology, Cosmogony, Space-time Continuum, Mathematics, Chemistry, Physics, Meteorology, Seismology, Botany, Zoology, Medicine, Agriculture, Geology, Environmental Science and Ecology, and Science and Technology have been discussed here in accordance with speculations of the Vedic bards gleaned from the hymns. Earlier scholars belonging to other disciplines, especially from Linguistics, Mathematics, Physics and Astronomy have tried their best to interpret the Vedas from the point of view of their particular disciplines. But, here, in this study, attempts have been made to analyse the Vedic verses in scientific terms adhering to various branches of modern science. The present discourse, no doubt, forms a strong base for any microscopic investigations of the Vedic thought and notion to be taken up in future by our inspired scholars and scientists.
Dr. Murthy marshals the whole extent of geological data from the Vedic/post-Vedic literatures and even later works like Varahamihiras Brhatsamhita to highlight the Vedic world-view of the earth, particularly the Vedic theory on Earth science.
Vedas are indisputably the oldest of mankinds documents. Which not just magnificently articulate the early civilized mans wonderment about the cosmos and his yearnings for the divine, but also unfold the foundations of many ancient sciences, like mathematics, astronomy, alchemy, metallurgy, botany and medicine. This book, however, is the first ever effort to show how Vedas embody the earliest discourses on the earth and the earth-related phenomena. Combining in him the acumen of a professional earthscientist and a highly proficient Sanskritist, Dr. Murthy marshals the whole extent of geological data from the Vedic/post-Vedic literatures, and even some of the later works, like Varahmihiras Brihatsamhita (of the 5th century ad) in his thematic effort to highlight the Vedic worldview of the earth and, importantly, how it almost approximates the projections of modern earthscience. Developed from over three decades of Dr. Murthys researches in ancient Sanskrit literature, the study employs contemporary scientific idiom to describe Vedic perception of the earth, its origin, shape, dimensions, constitution, movements, quakes/tremors, and its position vis-a-vis the solar system, stars and ethereal space. Also including, contextually, the Vedic idea of heliocentricity, the book puts forth the Veda-based methods for deciphering/predicting deep-focus earthquakes for future research and investigation. Together with a glossary of Sanskrit terms and relevant bibliographic references, this geological perspective on the Vedas will fascinate scholars, specialists and discerning readers alike.
Dr. N. C. Panda examines yoga-nidra as a scientific discipline the theory, its psychological basis, its techniques and applications to reveal its significance as a means of strengthening the bodys immune system and preventing and curing diseases and regulating ones life patterns. It involves comparative analyses like that of yogic trance and hypnotic trance and yoga-vedanta and Freudian psychologies.
Healing of body and mind through yoga is gaining immense significance at present as a world-wide science of therapy. In this context, yoga-nidra, a self-therapy technique of yoga and tantra, is important as an effective means of regulating the mind. In this volume, Dr. Panda, a noted philosopher and psychologist, yogi and tantrist, delves into the principles and practices of yoga-nidra based on materials from the tantras and Patanjali Yoga in an attempt to explain its benefits with special reference to modern medicine. The book presents yoga-nidra as a scientific discipline that is a potent means to strengthen the bodys immune system and thus to prevent and cure diseases and to regulate ones life patterns. It examines in detail the theory of yoga-nidra, going into the Indian concept of mind and personality. It establishes the psychological basis of yoga-nidra by comparing hypnotic trance and yogic trance and Freudian and Yoga-Vedanta psychologies. It then lucidly presents the techniques of yoga-nidra and deals with the applications of yoga-nidra with relation to curing of psychosomatic and other diseases of common occurrence and to solving current problems such as drug-addiction and stress-induced maladies. This well-conceived and thorough research work will prove useful to scholars of ancient Indian medical science and psychology, particularly those concerned with study of yoga vis-a-vis modern medical problems and systems. It will be of equal importance for the general readers owing to its interesting subject matter, simple style of presentation and easy adoption by the non-adepts.
The sound practice of yoga enables one to have a disease-free body and keen intellect. This book details the impact of various yoga practices on psychology and specifies that consciousness has a wider conation in yoga in developing one’s personality traits and leveraging them further to keep him/her happy and experience a blissful life.
Yoga psychology is both a positive and a normative science. It not only analyses human personality and its growth, but sets normative ideals and prescribes techniques to achieve such objectives, as well. Thus, expansion of consciousness and making oneself the master of his/her mind are the broad objectives of yoga psychology. The topological aspect of mind as described by Freud in terms of conscious, subconscious and unconscious levels was well detailed in the yogic literature, thousands of years ago. The sound practice of yoga enables one to have a disease-free body and keen intellect.
The book, thus, details the impact of various yoga practices on psychology and specifies that consciousness has a wider conation in yoga. Yoga presents vivid and sound meditation procedures for the attainment of psychic consciousness through the awakening of kundalini. Homeostasis or balance is the central principle in yoga psychology, and it holds that any sort of imbalance in the system physical, psychological or pranic creates disorders and the solution lies in rebalancing it. Here comes the role of yogic psychotherapies such as prarthana, mantra sadhana, spiritual couselling, pranayama, yajna, sankirtana, svadhyaya and vrata anushthana.
This volume enunciates that yoga psychology is an applied science, and thus has remedies for many individual and social problems. It deals at large with the application and benefits of yogic practices in developing ones personality traits and leveraging them further to keep him/her happy and experience a blissful life.
