The Torah reading of Va'etchanan is always read in close proximity to the unique holiday of Tu B'Av - the 15th of Av.
It's no wonder - both Va'etchanan and Tu B'Av speak of love: G-d's love for Israel, our love for G-d ,our love for one another, and our love for eretz Yisrael - the land of Israel.
Love makes it all possible.
