The highest compliment a listener can give a speaker. Arjuna says: Your words are like amrita — nectar. I keep listening, and the thirst never ends. There is no satiation. When this kind of bond forms between speaker and listener, knowledge truly flows.
Amritam — nectar. The Gita uses this word for knowledge repeatedly. Just as amrita does not quench thirst in the ordinary way but removes the fear of death, the words of the Gita remain fresh no matter how many times they are heard. Each listening reveals a new layer. The fear of the world diminishes with every hearing.
