This is volume one of the six-volume Shankara Source Book, which contains writings by Shri Shankara, arranged systematically by subject.Shri Shankara was a great philosopher-sage who expressed the non-dual teachings in such a complete and satisfactory way that his formulation has been followed by authentic teachers of the non-dual tradition ever since.Most of his writings are in the form of commentaries on revealed texts such as the principle Upanishads, the Bhagavad Gita and the Brahma Sutras, so what he said was placed around those texts, which are far from systematic.His aim was to demonstrate that underlying the apparent contradictions and differences on the surface, all the great revealed scriptures in fact point ultimately to one Supreme Truth. He wished to do this in order to overcome the confusion that was causing hardship to the people at large, and creating difficulties for dedicated seekers. Shankara probably lived in the 8th century, and died in his early 30s.Shankara considered other views in great detail, sometimes provisionally accepting elements of their arguments, and then pointing out where those views lead to difficulties. One of the great qualities of the non-dual teachings as formulated by Shankara is that they are able to recognise and incorporate what is valid and useful in other views.All this can make it difficult to find what Shankara said on particular subjects. To meet this difficulty, in the Source Book, the writings have been freshly translated, and brought together under subject headings. These in turn have been arranged in six volumes each covering one broad topic. These are: Volume 1 Shankara on the AbsoluteVolume 2 Shankara on the CreationVolume 3 Shankara on the SoulVolume 4 Shankara on Rival ViewsVolume 5 Shankara on DiscipleshipVolume 6 Shankara on Enlightenment
