The genuine guru is God’s representative, and he speaks about God and nothing else. The genuine guru is he who has no interest in materialistic life. He is after God, and God only.
Because he is the most confidential servitor of God, the guru is offered the same respect that we offer God. God is always God, a guru is always a guru. As a matter of etiquette, God is the worshipable God, and guru is the worshiper God (sevaka-bhagawan).
