This is ātmā, beginning. Asmin dehe. Within this body there is the soul. Dehino 'smin yathā dehe. Not this body is important. Body's nothing; it is dead matter. When Kṛṣṇa began His instruction and Arjuna was lamenting on the basis of this body: "If we kill our brothers, their wives will be widowed and they'll be bhraṣṭācāra(?), the varṇa-saṅkara will be there." Everything he was calculating on the basis of this body. All politics, sociology, they are going on the basis of this body. But Kṛṣṇa, as soon as He was accepted by Arjuna as guru . . . Śiṣyas te 'haṁ śādhi māṁ prapannam (BG 2.7): "Now, Kṛṣṇa, I accept You as my guru. Not as friend." Because friendly talking is useless waste of time. He accepted Him as guru. When guru speaks, you cannot argue. That is not the process. You should accept a guru who is infallible. Otherwise it is useless. He accepted guru Kṛṣṇa because Kṛṣṇa is infallible. If we accept guru, a bogus guru, then it is no benefit. Guru means Kṛṣṇa's representative. Guru, not that everyone can be guru.
It is said in the śāstra that ṣaṭ-karma-nipuṇo vipraḥ. Just like here it is accepted, brāhmaṇo nitarāṁ guruḥ. So generally, brāhmaṇa is accepted as guru by other orders of society. So, but śāstra says that brāhmaṇa is guru, that's all right, but ṣaṭ-karma-nipuṇo vipraḥ. One brāhmaṇa is very nipuṇa in his karma-kāṇḍīya knowledge, ṣaṭ-karma. Paṭhana-pāṭhana-yajana-yājana-dāna-pratigraha. This ṣaṭ-karma. Nipuṇa: very expert. Mantra-tantra-viśāradaḥ: and he's very expert in chanting the Vedic hymns and execution of tantra and so many things. Avaiṣṇavo gurur na syāt. If he's avaiṣṇava, if he's not attached with Viṣṇu, if he does not carry the order of Kṛṣṇa, gurur na sa syāt, sad-vaiṣṇavaḥ śva-paco guruḥ. But if a person is Vaiṣṇava, even if he's born in the family of a śva-paca . . . Śva-paca means dog-eaters, caṇḍāla. If he's a Vaiṣṇava he can become guru. And if one is a brāhmaṇa, if he's not a Vaiṣṇava . . . Naturally, brāhmaṇa means Vaiṣṇava. Brāhmaṇa means paṇḍita. Still, in India a brāhmaṇa is addressed as "Paṇḍitjī." Because a brāhmaṇa and mūrkha, rascal, this is contradictory. It cannot be. Unless one is highly learned, unless one has learned what is Brahman, he cannot become brāhmaṇa. Brahma jānātīti brāhmaṇaḥ.
So not only one should be brāhmaṇa, but he should become a Vaiṣṇava. Still higher. From brāhmaṇa platform he has to come to the Vaiṣṇava platform.
