Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura did not recognize the caste gosvāmīs because they were not in the line of the six Gosvāmīs in the renounced order who were direct disciples of Lord Caitanya Mahāprabhu-namely, Śrīla Rūpa Gosvāmī, Śrīla Sanātana Gosvāmī, Śrīla Bhaṭṭa Raghunātha Gosvāmī, Śrī Gopāla Bhaṭṭa Gosvāmī, Śrī Jīva Gosvāmī and Śrīla Raghunātha dāsa Gosvāmī. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura said that the gṛhastha āśrama, or the status of family life, is a sort of concession for sense gratification. Therefore a gṛhastha should not falsely adopt the title gosvāmī. The Worldwide Hare Krishna Movement has never conferred the title gosvāmī upon a householder. Although all the sannyāsīs we have initiated in the movement are young, we have awarded them the titles of the renounced order of life, svāmī and gosvāmī, because they have completely dedicated their lives to preach the cult of Śrī Caitanya Mahāprabhu. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura mentions that not only do the householder caste gosvāmīs disrespect the title gosvāmī, but also, following the principles of the smārta Raghunandana, they exhibit great foolishness by burning a straw image of Advaita Ācārya in a śrāddha ceremony, thus acting as Rākṣasas and disrespecting the cause of Hari-bhakti-vilāsa, which is the guide for Vaiṣṇavas. Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura says that sometimes these smārta caste gosvāmīs write books on Vaiṣṇava philosophy or commentaries on the original scriptures, but a pure devotee should cautiously avoid reading them.
