________________
Surendranath Dasgupta publication of this fifth volume of the History of Indian Philosophy by my husband. The Indian Government have permitted me to complete the remaining portion of the work as planned by the author. It is a great task and a very sacred obligation that I owe to my husband, both as his disciple and wife, and I do not know how far I shall be able to fulfil it. It all depends on God's will. But the work as it stands now is self-complete and will serve the need of enquiring minds about the different important schools of Saivism from the beginning of the Christian era. The references to texts and manuscripts have been duly checked. I beg the forgiveness of readers for any mistake that might remain.
