Sefer Ahavah

The Book of the Love of G-d

Commandments that are done frequently, which we have been commanded to do so that we may always love God and remember Him constantly--such as reciting the Shema`, prayer, tefillin, and blessings; circumcision is included, because it is a sign in our flesh to constantly remind us when we are not in tefillin or tzitzit or the like.
