"Devotee: "His Divine Grace Srila Bhaktisiddhanta Sarasvati accepted both Srila Bhaktivinoda Thakura and Srila Gaurakisora as his spiritual master.
"Prabhupada: Gaurakisora dasa... Bhaktivinoda Thakura was his father, and Gaurakisora dasa Babaji was treating Bhaktivinoda Thakura... Although he was householder and Gaurakisora dasa Babaji was renounced order, still he used to offer great respect to Bhaktivinoda Thakura, and Bhaktivinoda Thakura saw him a pure devotee; therefore he recommended his son, Bimala Prasada. His former name was Bimala Prasada, and he got this title Siddhanta Sarasvati by writing one thesis on astronomy, astrology, astrological calculation according to solar system. So he got this title Siddhanta Sarasvati. So this Siddhanta Sarasvati, Sarasvati title also accepted by sannyasa. Sarasvati, Bharati, Puri, Aranya, Bon, Parvat--there are ten names of sannyasa according to Mayavadi school, and according to Vaisnava school there are 108 names. So this "svami" and "gosvami," they're also included within that 108 names. So he accepted Gaurakisora dasa Babaji Maharaja his spiritual master. Yes?
"Devotee: Does our line of succession go directly to Gaurakisora dasa Babaji or to Bhaktivinoda Thakura?
"Prabhupada: No. Because he was treating Bhaktivinoda Thakura as his siksa guru, preceptor guru, so it is in the line.
"Devotee: But is Bhaktivinoda Thakura directly in succession from Lord Caitanya?
"Devotee: And Gaurakisora dasa Babaji also?
