There is a point in one’s practice when external (sadhaka deha) characteristics are understood by advanced Vaisnavas to be indicative of one’s internal life. This is what we find in Gaura-lila.
Thus from the lives and characteristics of Gaura’s associates some devotees have determined their position in Krsna-lila. But more often such “connections” are dismissed, sometimes too readily no doubt. Overall it is best to consult with those more advanced then ourselves in attempting to make such correspondence.
