The word “Purush" in its most social sense means man but in the aspect of Ayurveda, the term purush is repre- sented as atma or chetana dhatu (chetana-life and dhatu-element). The concept of the existence of atman (soul) is generally not accepted by modern science. According to Indian philosophy, the ultimate truth or absolute soul is one and he is Chetana (Sarvam Khalu Idam Brahm). Treatment of Panchmahabhut Sharir with presence of purush is known as Chikitsya Purush. Purush is supreme soul, pure conscious, unchanging, immortal neither birth nor death. It is essential for the creation of the universe and the living world. In the presence of purush gains knowledge through the mind. All the actions through karmendriyas, desire, pleasure, pain, life and death are per- formed. The purush (Kshetrajy) is lord of the house (Kshetra). The role of Purush in Srusti is laya & parlay which is the same as catalyst’s work in a reversible reaction. Keywords: Purush, Types, Karma Chikitsa, Chaturvinshatika, Rashi, Punarjanma

The number of superheavy particles with the mass of the Grand Unification scale with trans-Planckian energy created at the epoch of superheavy particle creation from the vacuum by the gravitation of the expanding Universe is calculated. In later collisions of these particles, gravitational radiation is radiated playing the role of bremsstrahlung for gravity. The effective background radiation of the Universe is evaluated.

Perhaps the most challenging problem confronting a cosmologist is to reconcile the observed large-scale structure of the Universe with the Friedmann-Lemaître cosmological models that have gained such widespread acceptance in recent years (cf. however the alternative viewpoint, as exemplified in this Symposium by Arp and others). In this review, I shall look anew at the spectrum of density inhomogeneities that survive decoupling of matter and radiation at z ~ 1000 and provide the primordial fluctuations that can eventually generate galaxies. A closely related matter, that of the associated fluctuations in the background radiation, is discussed elsewhere in this volume by Doroshkevich, Sunyaev and Zel'dovich.

AbstractQuantum gravitational effects may affect the large scale dynamics of the universe. Phenomenologically, quantum gravitational effect at large distances can be encoded in an extended uncertainty principle that admits a minimal measurable momentum/energy or a maximal length. This maximal length can be considered as the size of the cosmological horizon today. In this paper we study thermostatistics of an expanding universe as a gaseous system and in the presence of an invariant infrared cutoff. We also compare the thermostatistics of different eras of the evolution of the universe in two classes, Fermions and Bosons.

Against the background of a widespread tendency to diminish the sacred meaning of ritual actions, Terry Pratchett’s strive to shed light on the archetypal principles of mythological consciousness in contemporary folklore makes it possible to restorethe connection of the old rites, which have lost their original sense, with the worldview bases of modern society and to reacralize the profane. The Elements of mythological consciousness, manifested in ritual actions inherent in the modern functioning of English folklore, play a meaningful and compositional role in Terry Pratchett’s novels «The Reaper» (1991), «Lords and Ladies» (1992) and «Wintersmith» (2006). In Pratchett’s novels, Morris dance, which traditionally heralds the summer beginning, is balanced by a dance that marks the beginning of winter, indicating the natural cycles change. This manifests the functions of a sacred act: a dialogue between the world and a human, extracting the last from the flow of everyday life, and finalizing the routine work of a farmer. The study suggests the analysis of artistic means describing the Morris dance ritual as a marker of natural cycle changes and as evidence of a human establishing contact with natural forces, enshrined in the narrative and embodied in the dynamic form of dance. A common harvest festival turns into a Dance of the Death and a Maiden, which moves the process of harvesting and preserving the harvest into the realm of the sacred. The motive of the Death and a Maiden dance is being developed in the same compositional plane with the Morris dance motive, as an element of the narrative about the natural balance of life and death,fertility and harvest, about the cycle of the universe based on the love drive. The article examines the compositional elements of choreographic ekphrasis, highlights the significant elements of such a description, indicates the markers of the sacred and the profane, intrinsic to ritual dance in Pratchett’s novels. The conducted research allows to determine the role of dance in Pratchett’s literature work as a marker of the transition from one state to another, as well as season cycle changes.

N-body models running on supercomputers have been widely used to explore the development of structure in the expanding Universe. Recent results from the COBE satellite have provided a global normalisation of these models which now allows detailed comparisons to be drawn between observations and model predictions. Some predictions of the cold dark matter primordial perturbation spectrum are now shown to be consistent with surveys of galaxy redshifts.

Mythopoetic thinking operates on a binary principle, classifying all the phenomena of the macro- and microcosm. The opposition between cosmos and chaos, in other words, between life and non-being, was fundamental. Spaces assimilated by culture, an ordered world, symbolized by various images: a pillar, a mountain, a temple, a dwelling, was conceived as the center of the universe, which was opposed by chaos that threatened order. These ideas about the world order were actualized in the sphere of ritual, designed to preserve the order created in the first times by the ancestors and gods. The repetition of the original myth in the ritual was supposed to restore, renew the world order in the cyclical movement of time. This applied both to the general Egyptian holidays, such as the New Year, and to the initiations that members of society took place at one stage or another of the development of Ancient Egyptian culture. Transitional rites had two aspects: age and social. When passing the initiation, the members of the collective increased their social status, became initiated, moving from adolescence to marital relations, increasing their status in the collective. A special position was occupied by leaders and kings, who confirmed their high position in society during the holiday sd. Funerals were also considered transitional rites. Transitional rituals united ideas about such opposites as life and death, which was equated with the loss of a person's previous social status. An indispensable attribute of rituals was sacrifice, and not only bloody of animals, but also sacrifice with ancient ritual objects during the construction of temples on the site of ancient sanctuaries. Notable examples have been associated with the kings in charge of the prosperity of Egypt.

AbstractIn a cosmological perspective, gravitational induction is explored as a source to mechanical inertia in line with Mach’s principle. Within the standard model of cosmos, considering the expansion of the universe and the necessity of retarded interactions, it is found that the assumed dynamics may account for a significant part of an object’s inertia.

For more than half a century the theory that the universe is expanding has dominated cosmology. All current cosmological theories, from the various Big Bang models to the various Steady State models, explicitly assume an expanding universe. The evidence in favour of an expanding universe is purely circumstantial, and is based on a “sheer assumption”, (Hubble 1936a) that red-shifts in the light received by an observer on Earth from distant objects are caused by relative motion and hence may be interpreted as Doppler shifts. Hubble (1936b) continues: “…the ever expanding model … seems rather dubious”, and “On the other hand, if the recession factor is dropped, if red-shifts are not primarily velocity-shifts, the picture is simple and plausible. There is no evidence of expansion and no restriction of time-scale, no trace of spatial curvature and no limitations of spatial dimensions.” (Hubble 1936c). These statements are as true today as they were in 1936.

Our universe expands and cools. The electroweak (EW) phase transition, which endows masses to the various particles, and QCD phase transition, which gives rise to confinement of quarks and gluons within hadrons in the true QCD vacuum, Would presumably have taken place in the early universe, respectively, at around 10-11 sec and at a time between 10-5 sec and 10-4 sec, or at the temperature of about 300 GeV and of about 150 MeV, respectively. It is clear that the nucleon mass [Formula: see text], the axial coupling [Formula: see text], and other nucleon parameters evolve as the universe evolves, thereby serving as an important gauge for understanding the state of the Universe.
