Paṭhana pāṭhana, yajana yājana. Yajan means worshiping the Lord, and yājan means helping others. Priest, you know, priestly business. Priest means he helps the householders how to become Kṛṣṇa conscious. Purohita. Purohita means one who does welfare activities for the householders. Purohita.
Yajana yājana, paṭhana pāṭhana, and dāna pratigraha. Brāhmin business is to take charity from his disciples, followers, and again spend it for Kṛṣṇa's service. So these six kinds of business is for the brāhmaṇas, and they are suppose to be very learned, paṇḍitajī. Brāhmaṇa's position is paṇḍita.
So he was called paṇḍita, and he was actually paṇḍita, but he presented himself as a fool, although he was learned. He presented himself, "My dear Lord, people say that I am very learned, but actually I do not know what I am, wherefrom I have come, why I am suffering."
First of all, we do not know that we are suffering in every step. Why we are using this fan? Because we are suffering. Because the excessive heat we cannot tolerate—suffering. Similarly, in the winter season this wind will be another suffering. We have closed the doors tightly so that air may not come. Now the air is counteracting suffering, and in another season the same air will be suffering itself. So the air is the cause of suffering and it is the so-called cause of happiness also. Actually we are simply suffering. That we do not know.
But we get information from Lord Kṛṣṇa that this place is duḥkhālayam aśāśvatam (BG 8.15). It is a place for miseries. You cannot expect any happiness. That is our foolishness. That is our foolishness. We are trying to adjust things to become happy, but we are so foolish that we do not know there cannot be any happiness. This is called ignorance. This is called ignorance.
Therefore Bhāgavata says, parābhavas tāvad abodha-jāta (SB 5.5.5). Abodha-jāta, every one of us born foolish. And we are acting in different ways to become happy, but we do not know that in every step we are being defeated. We are fighting with the stringent laws of nature, struggle, but we are happy by some complacent thoughts that, "We have become happy. We are advanced. We are happy. We are becoming educated. We are advanced in science." But Bhāgavata says: "No, you are not advancing—you are simply being defeated, because you do not know how to get happiness. You are not trying for real happiness."
So this ignorance is dissipated by the knowledge of the Vedas. Lord Caitanya therefore has said—that Kṛṣṇa, He will say—that because we are so foolish we have forgotten how to become happy; therefore Kṛṣṇa has made so many Vedic literatures. Ataeva kṛṣṇa veda purāṇa korila (CC Madhya 20.117). So we should take advantage of these Vedas. Caitanya Mahāprabhu therefore says—we have already talked now—He says, sādhu-śāstra-kṛpāya yadi kṛṣṇonmukha haya (CC Madhya 20.120). This is Bengali—I think you will understand—I will explain in English also.
