The eternal religion of devotion doesn’t come by anything mechanical

“The Supreme Lord Śrī Kṛṣṇa Caitanya in pursuance of the teachings of the scriptures enjoins all absence of conventionalism for the teachers of the eternal religion. It does not follow that the mechanical adoption of the unconventional life by any person will make him a fit teacher of religion. Regulation is necessary for controlling the apparent worldliness of conditioned souls but no mechanical regulation has any value even for such a purpose.
