PREPARING TO SERVE HASHEM
When one wakes up in the morning, he is like a new person. This new person should wash his hands before he serves Hashem. Everything he does during the day should be aimed at serving Hashem. To show respect for the Great King - Hashem, a person also needs to clean himself when he wakes up, by going to the bathroom. Doing these things gives him a feeling of the holiness of Hashem.
