I was just thinking of teaching our students the pronunciation of the Sanskrit verses in the Bhagavad-gita, Srimad-bhagavatam, etc. and by Krsna's will you have already begun this. It will be a great help for me if the students are taught to pronounce in Sanskrit vibration. It will be another effect of transcendental sound vibration. But we should always remember that our aim is spiritual realization, so in such classes in the beginning there must be Kirtana and at the end also there must be Kirtana.
