Guru is very confidential servant of Kṛṣṇa. Why confidential servant? Because he is canvassing door to door, "Please become Kṛṣṇa conscious. Please surrender to Kṛṣṇa." Kṛṣṇa says to Arjuna, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66), and guru takes that very mission, but does not say like Kṛṣṇa, that "Your surrender to me." He says, "Surrender to Kṛṣṇa." One has to surrender to Kṛṣṇa through the via media of guru, directly. This is the process. Therefore guru accepts respects from the disciple not for his personal self, but conveying the respect to Kṛṣṇa. This is the process. Yasya prasādād bhagavat-prasādo yasyāprasādān na gatiḥ kuto 'pi **. If you cannot get the mercy of guru, then it is very difficult to approach Kṛṣṇa. We cannot approach Kṛṣṇa directly. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ (BG 4.2). That is the statement in the Bhagavad-gītā. Paramparā. Guru, he offers the same respect to his guru, his guru. It goes. In this way, it goes to Kṛṣṇa, paramparā system. Therefore it is stated, bhavad-anugrahāt. Bhavad-anugrahāt: "Please kindly become merciful upon me."
So in this way, one has to learn how to approach the Supreme Personality of Godhead. Our Vaiṣṇava system is ādau gurv-āśrayam. If we want to approach Kṛṣṇa, then in the beginning, ādau, the beginning is to take shelter of guru. That is being shown by Devahūti. Although He is son, (s)he is begging the mercy of Kapiladeva so that by His mercy she could understand what is devotional service and how to approach Kṛṣṇa. Tad etan me vijānīhi yathāhaṁ manda-dhīḥ. So this is very good qualification. Manda-dhīḥ: "My intelligence is not very sharp, manda." That is especially in this age. Of course, Kapiladeva and Devahūti was not in this age. Still, she is submitting because she happens to be woman, and although she is such exalted woman that she could give birth to the Personality of Godhead Kapiladeva—she was not ordinary woman—still, she thinks manda-dhīḥ: "I am less intelligence." Manda-dhīr hare: "My dear Kapila, You are Supreme Personality of Godhead, but I am manda-dhīḥ. My intelligence is not very sharp. Still, I want to understand the sublime subject matter, transcendental subject matter, from You. So it is possible." Bhavad-anugrahāt: "If You become merciful, then it is possible." This is the process.
So in order to get the mercy of guru, so yasya prasādād bhagavat-prasādaḥ **, we must search out a bona fide spiritual master, representative of Kṛṣṇa or Kapiladeva, and then we shall submit and offer service. In this way we shall please the guru, and if he is satisfied, then our business is complete. Yasya prasādād bhagavat-prasādo yasyāprasādān na gatiḥ kuto 'pi **. Therefore Caitanya Mahāprabhu recommended this process, this process, jñāne prayāsam udapāsya namanta eva. The process of understanding or approaching the Supreme Personality of Godhead is this. Caitanya Mahāprabhu approved this when He was discussing with Rāmānanda Rāya. So the process of approaching the Supreme Lord... So he first of all explained the varṇāśrama-dharma. Varṇāśramācāravatā puruṣeṇa paraḥ pumān, viṣṇur ārādhyate (CC Madhya 8.58). The human life is for viṣṇur ārādhanam. That is the human life, Viṣṇur ārādhanam. In varṇāśrama, the system... Cātur-varṇyaṁ mayā sṛṣṭam (BG 4.13), Kṛṣṇa says. Why establish this cātur-varṇyaṁ mayā sṛṣṭam? Because through the cātur-varṇya, systematic institution, following the rules and regulations of brāhmaṇa, kṣatriya, vaiśya, śūdra, one can approach Lord Viṣṇu. Viṣṇur ārādhyate. This varṇāśrama-dharma is very important. But Caitanya Mahāprabhu said that it is very difficult even to execute the rules and regulation of varṇāśrama-dharma in this age. Actually that is a fact. Therefore, after explaining varṇāśrama-dharma before Caitanya Mahāprabhu, He said, Caitanya Mahāprabhu said, eho bāhya: "Yes, it is one of the processes, but in this age it is very difficult." Who is going to be brāhmaṇa? It is very difficult. Especially it has become very difficult in India. We are advertising, we are soliciting, "Please come here in this Hare Kṛṣṇa Land and just become a brāhmaṇa-vaiṣṇava, and we shall try to serve you by giving you good place," but nobody is coming. Therefore it is very difficult to revive the old varṇāśrama-dharma culture.
