The Sutra of Ksitigarbha (Ksitigarbha-sutra) says:
Listen to the teachings with one-pointed faith and respect.
Do not censure or deride the speaker;
Honor your instructors—
Develop the idea that they are like a buddha.
Thus, as this says, view the instructor as being like a buddha. Eliminate disrespect; honor him or her with homage and goods by offering a lion throne and the like.
