God is one, but the ways to reach him are many! This central thought in Gita, has also been the dearly held ideal of Gurudev Sadhu Vaswani - an ideal which is upheld by Rev. Dada J P Vaswani, the mentor and spiritual head of the Sadhu Vaswani Mission. It is in this spirit of reverence and admiration that Rev. Dada offers for our reading, his own distinct tribute to the Great Sikh Gurus who have always been a tremendous source of inspiration to him and his ancestors. This book is much more that biographical account of the great Masters; nor is it another compendium of their invaluable teachings. Rev. Dada's stated wish is to talk about them and the values for which they stood, values which were translated into thoughts and words and deeds in their life and teachings.
