im sorry i dont know any books. . . but i just wanna say, that if u can read punjabi. . u will be so much more lucky, with more materials to choose from
i will always need translations. but what i really find very interesting is to read about the guru's and about their experiences. . . it gives u more insight into what they really were, i learn alot by hearing stories at the gurdwara as well as going online and searching about them, . . gurdware ton books vi mil jandia ah
