Lord Caitanya's travels to the Holy Places

“A pāṣaṇḍī is one who considers the great demigods such as Lord Brahmā and Lord Śiva equal to the Supreme Personality of Godhead, Nārāyaṇa.” (Hari-bhakti-vilāsa 1.117)  The conclusion is that we should not differentiate between the forms of the Lord. However, we should not equate the forms of the Lord with the forms of demigods or human beings. For instance, sometimes foolish  sannyāsīs  equate  daridra-nārāyaṇa  with Nārāyaṇa, and this is certainly offensive. To think of the body of the Lord as material is also offensive. Unless one is instructed by a bona fide spiritual master, he cannot perfectly understand these different forms.  Brahma-saṁhitā  confirms,  vedeṣu durlabham adurlabham ātma-bhaktau . One cannot understand the differences between the forms of the Lord simply by academic study or by reading Vedic literature. One must learn from a realized devotee. Only then can one learn how to distinguish between one form of the Lord and another. The conclusion is that there is no difference between the forms of the Lord, but there is a difference between His forms and those of the demigods.

TRANSLATION
“When the jewel known as vaidūrya touches other materials, it appears to be separated into different colors. Consequently the forms also appear different. Similarly, according to the meditational ecstasy of the devotee, the Lord, who is known as Acyuta [infallible], appears in different forms, although He is essentially one.”
