Ordinary person is not Caitanya Mahāprabhu. Caitanya Mahāprabhu is liberated. He is talking from the liberated platform. But not everyone is on the standard of Caitanya Mahāprabhu. Therefore first of all, one has to come to the standard of varṇāśrama-dharma. But Caitanya Mahaprabhu's position can be obtained, by the grace of Caitanya Mahāprabhu, by this saṅkīrtana movement. He is giving that.
That means we have to come to that position when we don't identify with this body. This varṇāśrama-dharma is identification with this body: "I am a brāhmiṇ." "I am a brāhmiṇ," what does it mean? This is bodily qualification, but I have got little more knowledge than others. I know what is Brahmin. But still, I am not a Vaiṣṇava. Unless I become a Vaiṣṇava, I come to the position of a brāhmiṇ and then I engage himself in the Brahmin's service, that is Vaiṣṇava. That is required. Simply . . .
But in order to raise oneself to the highest standard of life, these principles of varṇāśrama-dharma should be followed. You cannot become M.A. without becoming a student in the school and college. But if there is any special service . . . just like Dr. Rabindranath Tagore, he was given doctor title from the Oxford University.
