Sensitivity of the heart is the caring within in the gentlest of ways with another.
Sensitivity of the heart is the understanding, deep understanding one holds within that many don't take the time or caring of heart to truly understand. Everyone has sensitivities within, - areas of the heart that can be sensitive to situations, verbal expressions, attitudes, presentations in the physical and overall demeanor that another might not feel or even be aware of.
Sensitivity of the heart is being aware that there can be more in understanding a situation presented and a reaction put forth from another. Sensitivity of the heart is the awareness and knowingness that another can walk a different road of thought process than yourself.
Sensitivity of the heart is a knowingness within that there is a broader picture, wider scope from your thought process and honoring that within of another.
Sensitivity of the heart is showing love to another in your understanding. Love is all there is.
Go in this knowing.
