Swami Sivananda 
Autobiography of Swami Sivananda [EPUB ebook] 

A saint’s life is the ideal for all to emulate, a pattern for everyone who would make his own life sublime. It is an open book from which to learn the lessons of divine life. However much one tries to gain knowledge of spiritual truths from scriptures and texts, it is not until one actually sees someone in whom those truths shine exemplified that one is ready, willing and eager to realise those truths in actual daily life. That is the purpose that this inspiring book serves.
