We are not only gifted with life but also with death. Death follows us since we are born like a shadow of life itself. So where there is life there is death.
Parents not only give birth to their offspring but they also donate death to them. They pass on light of Love and also darkness of hate to their children in some or the other way. And the darkness of mind, heart or the material world achieves nothing but fear.
Fear is natural to every living being though it is only the imagination of an uncertain future.
In spite of knowing that fear is just an imagination ,it is extremely difficult to triumph over it.
