Lord Caitanya is Kṛṣṇa
He appears as a devotee to teach us how to love Kṛṣṇa. Read every pastime in that light.
“Similarly, although Lord Caitanya appears in the guise of a devotee, we should not foolishly think He is an ordinary human being; we should always remember that Lord Caitanya is Kṛṣṇa (God) Himself teaching us how to become Kṛṣṇa conscious, and we must study Him in that light.”
