Digging a well is a complex job. One needs to dig through soil and sand to reveal the natural water that flows beneath ground level. This was something that our forefather Yitzchak was quite familiar with, as he dug wells to provide water for his family. However it was more than a practical thing; it was in fact part of his spiritual role in this world to expose the hidden potential that is often not seen on face value.  This is an important tool for life, to never accept what appears on the outside but to always dig deeper.
