Caitanya Mahāprabhu is the spiritual master of the six Gosvāmīs of Vṛndāvana: rūpa sanātana bhaṭṭa raghunāth, śrī jīva gopāla bhaṭṭa dāsa raghunāth. So from the Gosvāmīs, then Kavirāja Gosvāmī, Viśvanātha Cakravārtī Ṭhākura, then Jagannātha dās Bābājī, then Bhaktivinoda Ṭhākura, Gaura-Kiśora dāsa Bābājī, Bhaktisiddhānta Sārasvatī. And we are servant of Bhaktisiddhānta. So there is a disciplic succession.
That paramparā should be followed. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). If we want to understand really Vedic literature, then we must follow the paramparā system.
