<p>6. Brief Resume of intended work:</p><p>6.1 Need for the Study</p><p>Parada is the most important and extensively used dravya in</p><p>Rasashastra. At the same time it is a chanchala dravya and hence niyantrana is</p><p> essential. The invention of yantra started with the niyantrana of Parada. Among</p><p> the yantras Dolayantra is the commonest and the most important yantra.</p><p>Dolayantra is specially useful in some Parada Samskaras and</p><p> shodhana of many Rasadi dravyas like Vaikrantha, Haratala, Gowripashana,</p><p>Manikya, Shanka, Shukti, Bhallataka, etc.</p><p>For any Parada yoga, Parada can be used after doing Ashta Samskara</p><p> or after Samanya Shodana or by extracting from Hingula. Among these Ashta</p><p>Samskarita Parada is ideal. Hence a detailed study of Ashta Samskara is</p><p> required.</p><p>Now a days many works are carried out on medicine, preparation,</p><p> procedure, analytical, toxicological, clinical studies, etc., but not much stress is</p><p> given on topics like standardization of Yantra etc. Keeping this into</p><p> consideration, standardization of Dolayantra is chosen and as Dolayantra is</p><p> commonly used in various Samskaras of Parada and Shodhana of many</p><p>Rasadi dravyas, the present study is taken up with reference to the Swedana</p><p>Samskara of Parada.</p><p>Parada is subjected to Swedana Samskara by using Kalka prepared of</p><p>Kshaaramla Dravyas keeping in Pottali in Dolayantra using Kaanji which</p><p> softens impurities.</p><p>Hence the need for this particular study is felt. 6.2 Review of Literature</p><p>Dolayantra is commonly mentioned in most of the Rasashastra books like Rasarnavam, Rasaratnasamuchchaya, Rasendra Chudamani, Ananda</p><p>Kanda, Parada Samhitam, etc.</p><p>In Rasarnavam1 it is described in the fourth chapter while explaining</p><p>Yantras, Mushas, etc.</p><p>In Rasaratnasamuchchaya2 it is described in the ninth chapter while explaining Yantras.</p><p>In Parada Samhitam3 it is described in the sixth chapter while explaining Yantras, mushas, etc.</p><p>The preparation of Kaanji used for Swedana Samskara of Parada is mentioned in various Rasashastra books like Parada Samhitam,</p><p>Bhavaprakasha Nighantu, Sharangadhara Samhita, Rasendra Bhaskara, etc.</p><p>Swedana samskara is also described in most of the Rasashastra books like Rasahrdayatantram, Rasaratnasamuchchaya, Rasatarangini,</p><p>Ayurveda Prakasha, etc.</p><p>Here Dolayantra according to Rasarnavam1, Rasaratnasamuchchaya2 and Parada Samhitam3, Kaanji according to Parada Samhitam3 and Swedana</p><p>Samskara according to Rasahradayatantram4 is taken up for the present study.
