The integration of the Ba’al Teshuva with (into) the Tzadik.
The Tzadik is revealing (into vessels and the world) and through the Tzadik the Ba’al Teshuva is able to live his life.
The Ba’al Teshuva adds two things:
1) His higher light.
2) He can take it lower into crude and coarse places.
The Tzadik’s Teshuva is his body, The Ba’al Teshuva’s Teshuva are his sins.
