Sunday Nissan 27, 5703 12th day of the Omer
Chumash: K'doshim, First parsha with Rashi.
Tehillim: 120-134.
Tanya: This quality of (p. 231)...The Esoteric Discipline. (p. 231).
The permissible, when done for one's pleasure, [1] is completely evil, as the Alter Rebbe writes in Tanya, Chapter 7, for we are commanded, "sanctify yourself with what is permitted to you." [2]
One must introduce sanctity into those matters that are permissible so that they serve the purpose of enhancing one's Torah, mitzvot, fear- of-G-d and good character traits.
Notes:
E.g. eating kosher meat but like a glutton, etc.
