For Hashem has heard the voice of my tears , Tehilim 6.
Infants cry for food , for comfort , for attention , for relief. As we mature , we cry for our needs that we yearn for , for a loss Hashem should protect us from , or out of joy Baruch Hashem.
The common denominator is the word bechi , for weeping , which is of the root word becho which means in you. Tears express the innermost , essential feelings of a person. That is why Hashem listens , because it is the authentic you.
Now may be a good time for a gem of Torah study.
