Śraddhā Debi Nāma Jāra Duiti Swabhāba Tāra
Śraddhā Dwibidha, Ata Eba Sādhana-bhakti-o Dwi-bidha — Two Kinds of Faith, and Therefore Two Kinds of Devotional Service in Practice (Sādhana-bhakti)
The goddess of faith (Śraddhā-devī) has two natures: faith rooted in rules and regulations and faith rooted in spontaneous attraction. When the soul follows the scriptures' teachings,
faith arises. The Vedas call this kind of faith vaidhī śraddhā (faith by following the rules and regulations of the scriptures).
Seeing how the residents of Vraja purely serve Lord Kṛṣṇa, the devotee finds faith arise within him. By great good fortune the aspiring devotee attains faith that is eager, spiritual,
pure, and filled with spontaneous love.
According to differences of faith, there are different kinds of devotional service. The Four Vedas say vaidhī and rāgānugā are the two kinds of devotional service. By practicing sādhana one eventually attains perfection. This the scripures of devotion describe.
Vaidhī bhakti is very slow and rāgānugā bhakti is very swifty. Following it, one swiftly comes to the rasas. By following the path of rāga one attains ruci (attachment) in his heart. The followers of Śrīla Rūpa Gosvāmī follow this path.
