If the only teacher you have is your suffering, you will need a substantial dose of it for the ego to dissolve. But if the power of spiritual teaching is already at work, then a minor event can dissolve the ego.
Eckhart TolleAs a child, a person builds up an egoic sense - the child has a name, has an "I," has a mind. But then, to awaken, a person needs to completely transcend that sense of ego.
