w/ever veer jee, I found this really amazing Kathaa titled Amrit Mukhtnama (the link is below). It very listenable, quite fast. In it bhai sahib explains when not to lie and when Guroo Sahib has said its better to not tell the truth etc.
It will answer all of your questions if you can make some effort to listen to it.
