In the 'Tantric Transformation' we are introduced to the sacred and ancient tradition of Tantra by a contemporary Tantric master, Osho. We are given a detailed map of Tantra: inner man, inner woman; the meeting of man and woman; the transformation of energy through sex, love and meditation. Based on the Royal Song of Saraha, we are not just introduced to an Asian sex tradition but with Osho we enter the higher levels of transformation. Here we find Tantra as a door to freedom: freedom from all mind-constructs, mind games; freedom from all structures and freedom from the other. Love and meditation merge and provide a path to liberation.'Tantric Transformation' is a very alive, concrete book for exploration of our own energy, of our own inner space. You don't just read Osho, you undefine yourself.

This volume contains the proceedings of the 2nd IFToMM Workshop for Sustainable Development Goals - I4SDG 2023 held in Bilbao, Spain, on 22-23 June 2023. The workshop papers are focused on those aspects of the theory, design and applications of Mechanism and Machine Science that are fundamental for moving towards sustainable development. The main topics of the workshop are: sustainable energy systems, robotics and mechatronics, biomechanical and medical systems, education, linkages, gears, transmissions and actuators, engines and powertrains, tribology, transportation machinery, service systems for sustainability, humanitarian engineering and socio-technical systems for sustainable and inclusive development. The contributions, selected through a rigorous international peer-review process, highlight many exciting ideas that will drive new research directions and foster multidisciplinary collaboration between researchers from different backgrounds.

Vols. 39-214 (1874/75-1921/22) have a section 2 containing "Other selected papers"; issued separately, 1923-35, as the institution's Selected engineering papers.
