Fasting which is not accompanied by good deeds

Hi,

"The completeness I desire is that which is recorded in Yirmiyahu, 'Let the one who is praised be praised for this: Have insight and know Me, for I am Gd who performs generosity and justice and righteousness in the land, this is what I desire.'

"This means: I desired for you to perform generosity and justice and righteousness in the land, to walk in My ways. Fasting and eating are not among My actions, for I neither eat nor drink. Fasting is non-eating, and it is not relevant for Me, for one cannot refrain from anything other than that which one normally practices."

(Abarbanel to Zecharyah 7, pg. 221)

Have a great day,
Mordechai
