Whatever is associated with the mind is bound to change. The truth is that which is changeless. It is the Self.
The change will only happen outside once we change within ourselves.
Nobody likes to let go of the ego- it is so precious to everyone. However, once you have attained a state of egolessness, the world won't disappear, as you may think it will. The world will continue, but a change takes place within you. Something is uncovered. You start seeing everything with the wonder and innocence of a child.
