Kadamba Kanana Swami recently started reading a three volume series on Srila Bhaktisiddhanta Saraswati Thakura complied by Bhakti Vikas Swami.
He stressed the following quote in the van drive from Heidelberg to Gundica temple in Germany, August 2009:
"Vani (association through words) is more important than vapu (association through physical presence) because vani leads to vapu, but vapu may not lead to proper vani."
