Download E-books Cutting Through Spiritual Materialism (The Clear Light Series) PDF

By Chogyam Trungpa

In this contemporary religious vintage, the Tibetan meditation grasp Chögyam Trungpa highlights the most typical pitfall to which each and every aspirant at the non secular course falls prey: what he calls spiritual materialism. The common tendency, he indicates, is to work out spirituality as a means of self-improvement—the impulse to improve and refine the ego whilst the ego is, via nature, basically empty. "The challenge is that ego can convert whatever to its personal use," he stated, "even spirituality." His incisive, compassionate teachings serve to wake us up from this trick all of us play on ourselves, and to supply us a much brighter fact: the real and joyous liberation that unavoidably contains letting cross of the self instead of operating to enhance it. it's a message that has resonated with scholars for almost thirty years, and continues to be clean as ever this present day. This new version features a foreword through Chögyam Trungpa's son and lineage holder, Sakyong Mipham.

Download E-books Light Scattering in Liquids and Macromolecular Solutions PDF

By P. N. Pusey (auth.), V. Degiorgio, M. Corti, M. Giglio (eds.)

This quantity includes many of the papers offered on the "Workshop on Quasielastic gentle Scattering reports of Fluids and Macromolecular suggestions" held at CISE, Segrate (Milano), Italy, from eleven to thirteen may possibly, 1979. Quasielastic gentle scattering (also referred to as self-beating spectroscopy or depth correlation spectroscopy) is the approach, brought by way of Benedek and coworkers and by way of Cummins and coworkers approximately 15 years in the past, during which dynamical information regarding a scattering medium is received during the dimension of the facility spectrum (or the depth correlation functionality) of the laser gentle scattered from the medium. The process acquired within the early seventies a substantial impulse from the improvement of real-time speedy electronic correlators. the purpose of the Workshop was once to collect a particular variety of researchers that allows you to speak about fresh advancements in quasielastic gentle scattering and similar optical equipment and to record approximately new purposes of the method in physics, chemistry and biology. the 1st days of the assembly have been dedicated to the oral shows of papers. within the 3rd day a casual consultation was once held which integrated a truly vigorous and thorough dialogue of the highlights of the Workshop. such a lot a part of the technical difficulties have been debated throughout the casual consultation and through the next visits to the sunshine scattering laboratory in CISE.
