The disciple should have the complete awareness that whatever the guru does is for his upliftment and good. Some may wonder whether such blind obedience to the guru is a kind of slavery. The truth is that the disciple is already enslaved to his own latent tendencies and ego. What the guru does is to rescue him from the bondage of that slavery.
The guru is like a booster rocket. Caught in many attachments, we are like satellites constantly circling around, caught in the gravitational field of the earth. The booster rocket that is the guru frees us from these bonds.
