The author traveled around India and talked with people who had actually known Gandhi and went to places where he had lived, while weaving in the history of his life. The book is not even all that long but it seemed to give a very well-rounded picture of its subject. I did not find it to be noticeably biased one way or the other.
One thing I found very interesting was the amount of effort Gandhi put into exhorting Indian villagers to improve the level of common sanitation. The book also discusses how Gandhi would urge his newlywed followers to remain celibate while he himself tested his commitment to celibacy with so-called "Brahmacharya experiments".
(By the way the book I bought had a much nicer cover than the one currently displayed on Amazon. Don't be put off by that because it really is a good book.)
I have read a lot of Ved Meta’s work over the years. He is well worth reading. Interestingly, he is also blind.
