Zos Chukas HaTorah 5746. (5772/2012).
The classic discussion of Para Aduma is enhanced in this Maamar. Para Aduma is "Chukas HaTorah" because it involves both Ratzu viShov. [On a level of Chakika]. This Maamar adds the issue (found in the Maamar of Para from 5700) that it touches on Yidden's free will, to error and correct and "burn" the Para (evil) altogether and to transform it.
