(Kadamba Kanana Swami, August 2013, Germany, Hamsaduta Seminar Part 2)
The gaudiya vaishnav mood is, “Where is Krsna?” We are always looking for Krsna. We see the six Goswamis were roaming around Vrindavan, always thinking, “Where is Krsna?”
So in this mood, everything reminds one of Krsna. The tamal tree reminds one of Krsna. So, as a devotee becomes more and more advanced, there are more and more udipan – there are more and more factors that remind one of Krsna.
