Śrī Caitanya Mahāprabhu warned all His followers not to become independent or impudent. Unfortunately, after the disappearance of Lord Caitanya Mahāprabhu, many apa-sampradāyas (so-called followers) invented many ways not approved by the ācāryas. Bhaktivinoda Ṭhākura has described them as the āula, bāula, kartābhajā, neḍā, daraveśa, sāni sahajiyā, sakhībhekī, smārta, jāta-gosāñi, ativāḍī, cūḍādhārī and gaurāṅga-nāgarī.
The āula-sampradāya, bāula-sampradāya and others invented their own ways of understanding Lord Caitanya’s philosophy, without following in the footsteps of the ācāryas. Śrī Caitanya Mahāprabhu Himself indicates herein that all such attempts would simply spoil the spirit of His cult.
