Chelek 27, Bechukosei 3

From The Sicha, Rabbi Chaim Wolosow by R Chaim Wolosow.

Three Levels of Giving

The Rebbe explains three levels of giving: measured charity, giving beyond a fifth for another’s need, and giving everything when the soul itself is at stake. These reflect stages in avodas Hashem and lead to the ultimate request—that Hashem redeem us from Golus with the complete Geulah.
