The Sadguru (teacher of true knowledge of God, who is also a human incarnation of God) gives the right knowledge, even without your service. You can serve Him only when you are convinced. Your service to Him will help Him help others. Infact a Sadguru does not need your service because He is God Himself. He can help others by His own powers. But you will not get the right benefit from Him, because you did not show gratefulness to Him. Suppose a doctor gives you medicines for some illness without asking for fees and you get cured. If you do not pay his fees due to your greediness, even though you are capable of paying, you will die with a new disease.

I dont get this.
Is the sadguru jesus christ or what?
If He is he is or not, how will your service to him, help him help others?
Isnt it an evidence that he lacks absolute power, thus not God?
