Therefore Caitanya Mahaprabhu says that,
trnad api sunicena
taror api sahisnuna
kirtaniyah sada harih
[CC. Adi 17.31]
Kirtaniya, this is lila-katha, lila-katha, kirtaniya. The… When you read or hear or chant about the pastimes of the Lord, that is also kirtana. And if you chant Hare Krsna mantra with instrument, that is also kirtana. There is no difference. So we must engage kirtaniyah sada harih. Either we should chant Hare Krsna mantra or we should read our books. This is wanted. Then we’ll be safe from maya. Otherwise, at any time, we’ll be victimized.
