Bind [my instructions] on your fingers; write them on the tablet of your heart.
Proverbs 7:3

Bind them on your fingers - Don't touch anything except through gloves of Torah. Let your touch be God's touch. Ask yourself, how would God touch, hold, and change this?

The tablet of your heart - Memorization is great, but this is more than that. It means to internalize it, and this only comes by repeated and habitual meditation. It means to think through the lens of Torah.
