Perhaps it was the time when the west didn't know the meaning of the word 'Yoga,' and that is why this book has so much importance. 'In search of a secret India,' narrates the quest of a early 20th century's European for search of the real yogis of India.
The author i.e., Paul Brunton 's desire to visit India was fueled by his mysterious meeting with few sacred souls in Europe during his ages to manhood. Although the book is published in 1934, still in 2016, it held my attention like no other book I have ever read. It's a wonderful book with rich vocabulary, and a lot to tell about India of the last century.
Author describes his meeting with a magician from Egypt at the hotel Majestic(now perhaps converted to a govt. building) at Bombay(now Mumbai), then an escape to Nashik to meet Mehar baba, then some very fruitful learnings from a Yogi from Madras at the bank of Adyar river... and so on and on.
Chapters are small and concise in every details of the story. There are many other places and renown people that you would know in this book. For travellers and spiritual heads, both should read this book at least once.
