The primordial push to pleasure is important to acknowledge because it explains the knee-jerk response we have to pleasure and pain and the patience that is required to reverse it. The spiritual path, with its open invitation to pain, goes against the grain of the very foundation of our ego-centered being.
This means that the path will give us exactly what we need and not necessarily what we want. We may not want to face our fear, loneliness, and heartache, but we need to if we want to grow. It is the adult version of having to eat our vegetables. They may not taste good, but fear, loneliness, and heartache can be good for us.
