The Torah¹ tells us "for six years you shall plant your fields... but in the seventh year the land should have complete rest, a Shabbat to G-d".

G-d created the world and then created man to maintain and perfect it. Progress and production is a partnership between G-d and mankind. G-d provides the raw materials, mankind works, and then G-d blesses his effort.

In a physical world caught up in materialism Man's work is quite evident, but in the rush and race for survival G-d's involvement often gets overlooked.

Unless we make an effort to focus. To stop, step aside, and set a time for observation and introspection. Thus Shmittah is to agriculture what Shabbat is to the working life: a G-dly devised reminder of what it’s all really about.

Every seventh day, we reorient: Shabbat. And every seventh year, we reaffirm: Shmittah.

Like Shabbat, Shmittah is a Divine mandate for obligated rest, which follows a universal cycle. On the designated Shabbat day we retreat from work, and during the designated Shmittah year we retreat from our fields.²

The Torah³ tells us that if we observe the Shmittah properly G-d will bless the efforts of the sixth year, resulting in enough produce for the next three years.
