There's a reason why he wrote this book , a person who believes in himself is actually the one who believes in God n these r not my words but the words from Bible , Qur'an and Geeta n same was said by Budhha . I read a lot of books on Different topics n people really mistook him. This was his letter to his friends from Central jail where they Questioned him ! Now if u knw a little abt Punjab n Gurus , u must knw they're ready to give Qurbaani ( sacrifice of life ) while the ones who believe in them doesn't. His Answer in good context was , if u really believe in God ? Why r u scared of the Qurbani ?
