BS’D
The Vilna Gaon ztk’l teaches in his commentary on Berachot that man posseses five powers
1) pulling power – when the food reaches his throat to pull it into the body
2) power to hold – hold the food so that it does not exit immediately and leave us unsatiated
3) power to digest
4) power to distribute – through which the body is nourished
5) power to reject – discard waste
Each one of these powers is contradictory yet they all work together in a coordinated fashion – for this we praise G-d’s wisdom for fashioning man so perfectly in the prayer Asher Yatzar.
