They are pure devotees, but they are guṇāvatāra. Just like Lord Brahmā is the supreme personality within this material universe. He's the father of all living entities. So they are . . . of course, if we very scrutinizingly study, Haridāsa Ṭhākura is, in devotional service, in greater position than Brahmā, although he is considered the incarnation of Brahmā, Brahmā Haridāsa.
So we should not be disturbed when we see Lord Brahmā and Lord Śiva is captivated in that way. We should take this instruction, that if Lord Brahmā, Lord Śiva becomes victim of māyā sometimes, what to speak of us? Therefore we shall be very, very careful.
There is chance of falldown even in the status of Brahmā and Śiva, what to speak of ordinary person. Therefore we should be very strongly inclined to Kṛṣṇa consciousness like Haridāsa Ṭhākura. Then we shall be able very easily to overcome the allurement of māyā. That is to be understood. Not that "Brahmā showed that," what is called, "weakness. He is weak, or he is less." No. That is for our instruction. Yes. Or first of all his. Yes.
