Crying comes from the deep,deep,deep heart. It's a very deep emotional event. Some of the crys can be suppressed,and some cannot be. There is a reason why we cry. We don't fully know the reasons.

God knows how many tears we have cried. Psalm 34:18 says,"The Lord is near to those who have a broken heart,And saves such as have a contrite spirit. (NKJV)
