Positive Mitzvah 71: The Guilt-offering
Leviticus 5:6 "And he shall bring his guilt-offering to the L-rd"

There are four forbidden acts listed in the continuation of this verse.

A person who commits any of these transgressions is commanded to bring a guilt-offering.

Nothingness is the medium through which all energy moves, from above to below and from below to above. Below, in Man, a sense of nothingness that transcends ego. Above, a Nothingness that transcends all boundaries and planes. The nothingness below fuses with the Nothingness above, locking heaven and earth in eternal embrace. That is why G-d is found amongst the truly humble.
