The true service of God is giving one's self over to God's will, whether or not the person is successful in performing all of his actions properly. When he is not successful at walking in the way Of God, he can still deepen his own self-nullification to God. He can play even by the lair of the scorpion and find the light of God there, and realize that despite what he may, or may not, have done, God is still with him.
The forces of evil Mt. Seir, is really just a ball of hair (שעיר - שער) which has no substance. It is just the voices of negativity that attempt to convince a person that whereas he may have had a life of meaning in the past, he is presently incapable of such a life. This is false. One needs to work on having a childlike approach. Just like a child is always aware of his parents' presence, so too we must make ourselves aware of the presence of God.
