This week's "Toras Avigdor" The Precious Mind from Reb Avigdor Miller z"l is an amazing masterpiece.
excerpt:
And that’s the great lesson of why the head was carried up to the mizbeach before all the other parts of the korban olah. It was brought up on the mizbeach first because that’s the most important thing in our lives, our minds. And that’s why the first of all the weekday brachos is Atah Chonein, because that’s number one! To thank Hakodosh Boruch Hu for the great gift of sanity. And to remember always that it’s this gift that is our most precious possession in this world – and that’s why we’ll develop it and guard it more than anything else.
