Srila Bhaktisiddhanta Goswami Maharaja's commentary on this verse:
In the course of argument and counter-argument, Śrī Advaita Prabhu
became very angry and said,
“Your behavior is similar to that of a dārī
sannyāsī who eats fish and meat and who brags that he has given up the
dress of a householder and become naked. You are just like the Tantric
sannyāsīs who are envious of the Vaiṣṇavas, who are attached to sense
gratification, who are followers of Śākta philosophy, and who try to
protect their reputation as sannyāsīs by indulging in pañca-makāra
[Pañca-makāra refers to māṁsa, madya, matsya, mahila, and maithuna—
meat, wine, fish, women, and sex]. Whimsical behavior can never be the characteristic of a sannyāsī under the shelter of the Vedas.”
After reading these statements, foolish people should not consider Śrī
Baladeva-Śrī Nityānanda Prabhu as fallen from sannyāsa and proper
behavior. It should be known that one who exposes his natural foolishness
by failing to understand the actual purport of Advaita’s statements is
unqualified to understand the characteristics of Nityānanda Prabhu. These
sarcastic or disguised as blasphemous statements of Śrī Advaita are
simply a ploy to increase the sinful propensities of those who eat fish and
meat. Those not understanding the purport of these words who are most
unfortunate and bereft of intelligence take shelter of worldly sinful
activities and traverse the path to hell. Those who are easily influenced
by the word jugglery of others can never become intelligent devotees of
Kṛṣṇa.
