Two Kinds of Faith

Srila Bhaktivedanta Narayana Gosvami Maharaja : On Raganuga-bhakti - there are two kinds of sraddha (faith)
It may be noted, however, that Srila Visvanatha Cakravarti Thakura is not describing sakhya and vatsalya-bhava in Raga-vartma-candrika; he is presenting only gopi-bhava. In that regard, in order to attain that bhava, one will especially hear from a raganuga-bhakta the portions of the Tenth Canto discussing Krsna’s relationship with the gopis, namely Gopi-gita, Yugala-Gita, Bhramara-Gita, Pranaya-gita, and Venu-gita.
One who has samskaras (impressions in the heart) from having taken proper association in his previous births will be able to cultivate greed and achieve gopi-bhava by reading sastra; he will not have to rely on sastric logic to convince him. For such a person, this treatise will be the candrika for discovering the path of raganuga.
The author first explains that there are two kinds of sraddha (faith) – vaidhi and raganuga – which result in two kinds of bhakti – vaidhi-bhakti and raganuga-bhakti. Both types of sraddha are achieved through the association of qualified Vaisnavas. Where entrance in bhakti is impelled by fear, where it is induced by the injunctions of sastra that instruct everyone to perform bhakti to Krsna, otherwise they will go to hell – this is called vaidhi-bhakti.
In this way one may enter bhakti by fear; or, one may be impelled by the order of sastra which is based on yukti, reasoning. For example, sastra has ordered:
sa vai pumsam paro dharmo yato bhaktir adhoksaje
ahaituky apratihata yayatma suprasidati
["The highest pursuit for all humanity is suddha-bhakti – bhakti performed in order to please Krsna, the transcendent Lord Adhoksaja, by all one’s efforts of body, mind, and soul. Such uttama-bhakti is continuously performed without any personal desire (anyabhilasita-sunyam) and without any break. In this way one can fully satisfy the self (atma)." (Srimad-Bhagavatam, 1.2.6)]
By hearing such instructions, many people enter bhakti, and such bhakti is called vaidhi-bhakti.
Sripad Tamal Krsna Gosvami: This is vaidhi-bhakti.
Srila Narayana Gosvami Maharaja: And, that bhakti which is based only on genuine greed is called raganuga-bhakti. Such greed is generated by hearing the pastimes of Krsna and the gopis described in Srimad-Bhagavatam, by reading the books of the Gosvamis, and especially by being in the association of a raganuga-bhakta. Without the association of such raganuga-bhaktas, the pastimes of Krsna and the gopis will not be properly understood.
