Shema: Environment
“Teach them thoroughly to your children and speak of them while you sit in your home, while you walk on the way, when you retire, and when you arise.”
You have to create an environment for Torah study in every aspect of your life. When you are traveling means as you are traveling on your spiritual journey—as you are growing. Torah has to be a part of your path of growth. It has to be foremost on your mind—when you go to sleep and when you wake up.
