A good teacher is the one who follows the principles of listening first, teaching in detail till confusion arises and then teaching with reasoning while going into the minutest details and finally summarizing the ‘take–home’ messages.

This is how Lord Krishna discoursed to Arjuna in Bhagavad Gita. In the first chapter, he only listens; in the second, he gives detailed counseling and from chapters 2 to 17, he gives reasoning and in 18th chapter, he revises.
