Bhaktivinoda Thakura explains in his Sri Chaitanya-Siksamrta that vidhi, regulation that forms the basis of vaidhi-bhakti, is not contrary to raga (spontaneity). Pure vidhi is helpful to raga, and pure raga is a result of vidhi that is in harmony with the will of God. Vidhi helps us cure diseased raga, and when raga is healthy, vidhi retreats.
