________________ PREFACE The present volume is a miscellany of critical studies and critically re-edited texts on the subject of meditation There is diversity of language and also of treatment of the topic. Some chapters are written in Hindi and others in English. Some of the original texts compiled in it are in Prakrit and others in Sanskrit. The treatises of as many as six distinguished Jaina thinkers, viz. Umasvati, Siddhasena Divakara, Jinabhadragani Ksamasramana, Siddhasenagaoi, Virasenacarya and Abhayadevasuri, on the subject of meditation have been brought together in one volume. All the texts have been thoroughly revised on the basis of internal evidence and the appropriateness of the meaning. I am grateful to the original editors of the texts that I have compiled in this volume.

The first chapter contains the text of the Sthananga Sutra on dhyana and the Sanskrit commentary thereon by Abhayadevasuri. The classical theory of the four varieties of meditation has received a lucid treatment here. The second chapter, which is written in Hindi, gives a general view of Jaina yoga, delineating the development of the concept through the ages. In the third chapter, a short critical and comparative commentary is written in Hindi on the Dhyanadvatrinsika of Siddhasena Divakara. The fourth chapter deals, in English, with the ten stages of the concentrated mind as given in the fifth chapter of the Ayaradasao. The fifth chapter contains the critically re-edited text of Siddhasenagani's commentary on the Tattvartha-Bhasya of Umasvati. The text has been revised on the basis of the photocopy of a fairly correct manuscript, belonging to Muni Sri Jambuvijayaji, obtained through Sri Joharimalji Parakh of Sewa Mandir, Rawati, Jodhpur. I am grateful to both of them for the courtesy and kindness shown to me by them. The sixth chapter gives the text of the Dhyanasataka ascribed to Jinabhadragaoi Ksamasramana. In the seventh chapter the portion of Virasena
