CC Madhya-lila

If one does not come to the platform of spontaneous service in the beginning, he must adopt regulative service according to the instructions of the spiritual master. This regulative service is called vaidhī bhakti.

CC Madhya 22.109, Purport:

Dormant love for Kṛṣṇa exists in everyone's heart, and it simply has to be awakened by the regulative process of devotional service. One has to learn to use a typewriter by following the regulative principles of the typing book. One has to place his fingers on the keys in such a way and practice, but when one becomes adept, he can type swiftly and correctly without even looking at the keys. Similarly, one has to follow the rules and regulations of devotional service as they are set down by the spiritual master; then one can come to the point of spontaneous loving service. This love is already there within the heart of everyone (nitya-siddha kṛṣṇa-prema).

Spontaneous service is not artificial. One simply has to come to that platform by rendering devotional service according to the regulative principles. Thus one has to practice hearing and chanting and follow the other regulative principles by washing the temple, cleansing oneself, rising early in the morning, attending maṅgala-ārati and so on. If one does not come to the platform of spontaneous service in the beginning, he must adopt regulative service according to the instructions of the spiritual master. This regulative service is called vaidhī bhakti.
