Premodern Yoga Traditions and Ayurveda https://journals.library.ualberta.ca/hssa/index.php/hssa/article/view/25 <p>The research for this article was prompted by the question: were Yoga and Āyurveda as intimately connected in premodern times as they to seem today? It attempts to give a preliminary answer by assessing the influence of Āyurveda on a corpus of mediaeval Yoga texts, in terms of shared terminology, theory and praxis.&nbsp;The date of this corpus ranges from the eleventh to the nineteenth century CE, and all of its texts teach physical techniques and an ascetic state of dormant meditative absorption (<em>samādhi</em>), either as auxiliaries within a system of Yoga or as autonomous systems in themselves. The physical techniques became known as Haṭhayoga and the ascetic state of <em>samādhi</em> as Rājayoga, and the texts in which they appear posit the practice (<em>abhyāsa</em>) of Yoga as the chief means to liberation (<em>mokṣa</em>). The article begins with a discussion of the terminology in these texts that is also found in the&nbsp;<em>Bṛhattrayī,</em> that is,&nbsp;the <em>Carakasaṃhitā</em>, the <em>Suśrutasaṃhitā</em> and Vāgbhaṭa’s <em>Aṣṭāṅgahṛdayasaṃhitā.&nbsp;</em>It proceeds to discuss the relevant theory (digestive fire, humoral theory, vital points, herbs) and praxis (<em>āsana</em>, <em>ṣaṭkarma</em> and therapy or<em> cikitsā</em>) of the yoga texts in question in order to assess the possible influence of Āyurveda. </p> Jason Eric Birch ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2018-04-18 2018-04-18 6 1 83 10.18732/hssa.v6i0.25 The Kriyākramakarī’s Integrative Approach to Mathematical Knowledge https://journals.library.ualberta.ca/hssa/index.php/hssa/article/view/23 <p>The purpose of this paper is to review the general organization of knowledge in the <em>Kriyākramakarī</em>, a sixteenth-century treatise of Kerala mathematics. Specifically, I will argue that the authors' interest in justification or proof is integrative, rather than hierarchical or cumulative. In other words, the purpose of proofs in the <em>Kriyākramakarī</em> is to connect various different aspects of mathematics, rather than just establish results by means of previously known results. &nbsp;&nbsp;&nbsp;&nbsp;</p> Roy Wagner ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2018-04-30 2018-04-30 6 84 126 10.18732/hssa.v6i0.23 A Critical Edition of the Candrārkī of Dinakara https://journals.library.ualberta.ca/hssa/index.php/hssa/article/view/35 <p>A set of tables devoted to solar and lunar phenomena entitled the <em>Candrārkī</em> &nbsp;was prepared in Sanskrit by the sixteenth-century Indian astronomer Dinakara.&nbsp; Along with the tables, Dinakara composed a short accompanying text which instructed the user how to extract and manipulate the tabular data to construct their own calendar&nbsp;for&nbsp;any desired year and geographical circumstances. &nbsp;The work proved to be popular. &nbsp;Based on a small fraction of the extant manuscripts, we present a critical edition of the text together with a discussion of the challenges raised while preparing the edition.</p> Aditya Kolachana Clemency Montelle Jambugahapitiye Dhammaloka Keshav Melnad Mahesh K Pravesh Vyas Krishnamurthi Ramasubramanian M.

It is argued that a major source of these doctrines is Sahl ibn Bishr’s Arabic-language intro­duction to astrology (ninth century), possibly in abbreviated or paraphrased form. Several of the constituent ideas have been imperfectly understood by their Indian epitomists, resulting in reinterpretations and innovations.</p> Martin Gansten ##submission.copyrightStatement## http://creativecommons.org/licenses/by-sa/4.0 2018-08-30 2018-08-30 6 162 199 10.18732/hssa.v6i0.34
