T23 (Tinyana) PNC - Joy that Pursues Atzvus and Drags it Inside

Picture dancers in a circle. Sometimes they grab a sad person standing outside and force him into the ring until he is dancing too. So in serving Hashem: there is a small joy that simply pushes sadness aside, and there is a higher joy that hunts the sadness down and drags it into the dance. The verse 'Sasson ve-simchah yasigu, ve-nasu yagon va-anachah' (Yeshayah 35:10) is read backwards: the joy chases sorrow, catches it, and forces it into the holiness it was fleeing. Pure sorrow runs from joy because, being from the other side, it does not want to become a vehicle for kedushah — so we must coerce it in.
