The sixth aliyah begins with the well-known "Shema Yisroel" prayer that we say every morning and evening and that we are sure to teach our children. It contains the mitzvot of, among other things, tefillin and mezuzahs. In fact, this passage is part of what is written on the parchment inside our tefillin and inside our mezuzahs. The words "You shall speak of them when you sit in your house, and when you walk on the road, when you lie down, and when you rise" are contained here. "When you sit in your house" can be interpreted to mean, "when a soul is in heaven waiting to be born." "When you walk on the road" means when the soul in placed in a body who then lives its life on earth. "When you lie down" means when the person passes away. "And when you rise" means when that the person is resurrected during "techiyas hameisim" (resurrection of the dead) when Moshiach comes, may he come speedily in our days, Amen.
The aliyah then continues with G-d promising us a land of plenty, but that we should not forget G-d, who brought us out of Egypt, and out of slavery.
