The ego eventually comes to recognise a pattern involved in this process of growth and it resists it; and therefore, we become stuck, fixated, locked into an ego level of development. The ego then becomes a barrier that we have to learn to transcend, to leave behind. We cannot follow the Master who calls us, unless we leave self behind. So the ego is like a boat that takes us across a river to the other shore, but it then has to be left behind.
