2 types of Sraddha

"First, the prospective devotee develops śraddhā or faith. Śraddhā means to have firm trust in the import of the scriptures dealing with bhakti. It also means to have a genuine desire to enthusiastically undertake the activities (sādhana) described in those scriptures. These two types of faith may be either natural (svabhāviki) or being convinced by the preaching of another (balutpadita)."
