Pradyumna: "One has to learn Kṛṣṇa consciousness or pure devotional service from the authorities by spontaneous loving service."
Prabhupāda: Spontaneous. This service should be spontaneous, not forced. Just like a father loves his son spontaneously. A young man likes to love a young girl spontaneously. So bhakti should be like that. As soon as one hears the name of Kṛṣṇa, immediately, spontaneously, he should be ready to serve Him. That is pure devotion. Not that forced. In the beginning, we have to force, that "You rise early in the morning. There is maṅgala ārātrika. You have to perform it." But when this function will be done spontaneously, "Oh, this is the time to offer maṅgala ārātrika to my Lord..." That is wanted. That is wanted. Not that "Oh, it is a heavy burden to rise early in the morning and to offer maṅgala ārātrika." That is not spontaneous. But one has to act under the direction of spiritual master and śāstra, which is called vidhi-bhakti, regulative devotional service, he comes to the platform of spontaneous service.
We have got an example in this connection. Formerly there was child-marriage. Boys and girls were married at the age of ten years, twelve years. So at that time, there was no practically love. But the guardians, they induced the girl to go and offer her husband some eatables, to give her some service. In this way... That was just like regulative. But when they actually come in the platform of attraction, there is no need of direction. So the spontaneous love, when spontaneously we shall serve Kṛṣṇa, without any obligation, without any force, that is required. Spontaneous love, rāga-mārga.
