Machshava:

Sukkot 

Description

Hoshana Rabbah is the pinnacle of Sukkos, din on mayim (rainfall) is the din on life itself. The arava has no flavor and no scent, it has the most desperate need for water and quickly wilts - and that is it's secret. Rainfall as a mashal for Hashem's word, vegetation represents fulfilling Hashem's word. The secret of Techias Hameisim.
