Sri Caitanya Mahaprabhu, who is the supreme controller, the one Personality of Godhead, has ecstatically become a devotee, yet His body is transcendental and not materially tinged.
There are different tattvas, or truths, including isa-tattva, jiva-tattva and sakti-tattva. Isa-tattva refers to the Supreme Personality of Godhead Visnu, who is the supreme living force. In the Katha Upanisad it is said, nityo nityanam cetanas cetananam: the Supreme Personality of Godhead is the supreme eternal and the supreme living force. The living entities are also eternal and are also living forces, but they are very minute in quantity, whereas the Supreme Lord is the supreme living force and the supreme eternal. The supreme eternal never accepts a body of a temporary material nature, whereas the living entities, who are part and parcel of the supreme eternal, are prone to do so. Thus according to the Vedic mantras the Supreme Lord is the supreme master of innumerable living entities.
The Mayavadi philosophers, however, try to equate the minute living entities with the supreme living entity. Because they recognize no distinctions between them, their philosophy is called Advaita-vada, or monism. Factually, however, there is a distinction. This verse is especially meant to impart to the Mayavadi philosopher the understanding that the Supreme Personality of Godhead is the supreme controller. The supreme controller, the Personality of Godhead, is Krsna Himself, but as a transcendental pastime He has accepted the form of a devotee, Lord Caitanya Mahaprabhu.
As stated in the Bhagavad-gita, when the Supreme Personality of Godhead Krsna comes to this planet exactly like a human being, some rascals consider Him to be one of the ordinary humans. One who thinks in that mistaken way is described as mudha, or foolish. Therefore one should not foolishly consider Caitanya Mahaprabhu to be an ordinary human being. He has accepted the ecstasy of a devotee, but He is the Supreme Personality of Godhead. Since Caitanya Mahaprabhu, there have been many imitation incarnations of Krsna who cannot understand that Caitanya Mahaprabhu is Krsna Himself and not an ordinary human being. Less intelligent men create their own "Gods" by advertising a human being as God. This is their mistake. Therefore here the words tanra suddha kalevara warn that Caitanya Mahaprabhu's body is not material but purely spiritual. One should not, therefore, accept Caitanya Mahaprabhu as an ordinary devotee, although He has assumed the form of a devotee. Yet one must certainly know that although Caitanya Mahaprabhu is the Supreme Personality of Godhead, because He accepted the ecstasy of a devotee one should not misunderstand His pastimes and place Him in exactly the same position as Krsna. It is for this reason only that when Sri Krsna Caitanya Mahaprabhu was addressed as Krsna or Visnu He blocked His ears, not wanting to hear Himself addressed as the Supreme Personality of Godhead. There is a class of devotees called Gauranga-nagari, who stage plays of Krsna's pastimes using a vigraha, or form, of Caitanya Mahaprabhu. This is a mistake that is technically called rasabhasa. While Caitanya Mahaprabhu is trying to enjoy as a devotee, one should not disturb Him by addressing Him as the Supreme Personality of Godhead.
