When we give someone a hug, we are implicitly showing we are one with them. It is a gesture expressing connection, not just physically but spiritually. A hug in a marriage is a display of a commitment lasting forever. A hug to a family member embodies a blood connection as well as a spiritual one. And a hug to a best friend implies dependability for a lifetime.
A hug brings inner warmth, both to the giver and to the receiver. Today, give at least one person a hug. This will bring a spiritual smile to both of you.
