Preparing for Yud Shevat, world-renowned teacher Rabbi YY Jacobson, presented to the Monsey community part six of the incredible and revolutionary Maamar Basi Legani 5723 (1963), said by the Rebbe exactly 60 years ago. 

The theme of the 6th class of the maamar is how all matter, all chemistry, science and physics is the embodiment of Divine light. The distinct worlds are diverse ways in which we define matter.
