In this shiur, delivered in Sharfman's, Rav Burg explains (based on a sicha from the Lubavitcher Rebbe) why Shaatnez is sometimes permitted, why Kilyaim is never permitted and why we might have thought that milk and meat would be permissible for the eating of Kodshim. Ultimately, in the times of Mashiach, one will be allowed to eat milk and meat together and this represents the perfect balance in our relationships.
