The nature of ego is to latch on to that which temporary. If we chose to let that go, then not only do we free ourselves from a major source of pain, but we will also be open to the gift of the next stage of life that is being presented to us by the universe.
Our ego chooses physical things that provide temporary happiness. Achievements, possessions, talents give us happiness that ends once the “newness” wears off. If we are to look in ones closet, garage or attic, we would find old awards, clothes, or other physical things that made us happy.
This is temporary and once time passes, the ego will search for another physical thing to fulfill our desires. When we place our ego aside and choose a spiritual path aligned with God and the Light, we find that happiness can be never ending.
