Most biographies are very poorly written. Why ? Because the people who write it are clueless about the inner hardship and turmoils of the subject
I recently read the biography of yogi Harnath by Makrand Dave. His book could not focus on the life of Harnath but was more focused on him, his own views and interpretation and his interaction
This never does justice and could be a hindrance to spiritual progress. General public try to emulate or copy what great people say or do. This is not right
One example in the book is a direct copy of vivekananda and Ramkrishna dialogue – if you are in a lake of Amrut where would you take a dip
So should books be written ? Yes and no. Yes for the casually interested people but does not help advanced Yogi
