activities. One should not accept a rascal as an incarnation of God but should test his ability to act as the Supreme Personality of Godhead. For example, Kṛṣṇa taught Arjuna in  Bhagavad-gītā , and Arjuna also accepted Him as the Supreme Personality of Godhead, but for our understanding Arjuna requested the Lord to manifest His universal form, thus testing whether He was actually the Supreme Lord. Similarly, one must test a so-called incarnation of Godhead according to the standard criteria. To avoid being misled by an exhibition of mystic powers, it is best to examine a so-called incarnation of God in the light of the statements of  śāstras . Caitanya Mahāprabhu is described in the  śāstras  as an incarnation of Kṛṣṇa; therefore if one wants to imitate Lord Caitanya and claim to be an incarnation, he must show evidence from the  śāstras  about his appearance to substantiate his claim.

TRANSLATION
Seeing that the Māyāvādīs and others were fleeing, Lord Caitanya thought: I wanted everyone to be immersed in this inundation of love of Godhead, but some of them have escaped. Therefore I shall devise a trick to drown them also.
PURPORT
Here is an important point. Lord Caitanya Mahāprabhu wanted to invent a way to capture the Māyāvādīs and others who did not take interest in the Kṛṣṇa consciousness movement. This is the symptom of an  ācārya . An  ācārya  who comes for the service of the Lord cannot be expected to conform to a stereotype, for he must find the ways and means by which Kṛṣṇa consciousness may be spread. Sometimes
