Vedic literatures and Vedas, they are all the same, they are called śruti and smṛti. So, they recommend that if you..., tad vijñānārthaṁ sa gurum eva abhigacchet (MU 1.2.12). If you are actually you are anxious to learn that transcendental science, then you should accept, you should approach a bona fide spiritual master. Prahlāda Mahārāja also says the same thing, guru-śuśrūṣayā. Guru means heavy, or superior. So you can satisfy superior by your service, not by challenging, that is not possible. Guru-śuśrūṣayā. Guru-śuśrūṣayā bhaktyā. And what kind of śuśrūṣayā? Bhaktyā. Just like a paid servant, he is also engaged in satisfying the master very nicely, very faithfully, but there is no bhakti. Why? Because he is after the money the master pays. He does not serve the master, but he serves the money. He is thinking always that "I am getting so much money from this person. If I don't satisfy him, then I may be dismissed. So I will have no money." But here it is said bhaktyā. Bhaktyā means without any, I mean to say, material concern. Bhakti is applicable in the spiritual world. Bhakti is transacted, the business of bhakti is transacted in the spiritual world. Or where there is devotional service, there is spiritual world, there is no material world. So guru-śuśrūṣayā bhaktyā sarva-labdhārpaṇena ca.
So it is very difficult (indistinct). Just like Bali Mahārāja gave everything, everything. Sarva-labdhārpaṇena, labdha means profit. So one should be prepared to sacrifice all profit, all gain to the spiritual master. I had one Godbrother, Professor Sannyal, he showed example. Of course, amongst our students there are many. They have dedicated their life, and what to speak of anything, everything. That is the process here, sarva-labdha arpaṇam. Arpaṇam means delivering, "Sir, I have got this. Here you are, you take this." Then śuśrūṣayā. So serve him with devotion, with faith, and giving him everything. Guru-śuśrūṣayā bhaktyā sarva-labdhārpaṇena ca, saṅgena sādhu-bhaktānām. And in association with sādhu. Sādhu means those who are engaged fully, fully in the Kṛṣṇa's devotional service. Sādhur eva sa mantavyaḥ (BG 9.30). Api cet su-durācāro bhajate mām ananya-bhāk. Ananya-bhāk, without any deviation. Those who are engaged in the service of Kṛṣṇa, he is sādhu. It is not simply by changing dress. Sādhu means sādhavaḥ sādhu-bhūṣaṇām. Sādhu means honest, sadācārī, good character. But the ultimate aim(?) is, as Kṛṣṇa recommends, that api cet sudurācāro bhajate mām ananya..., not that one has to adopt all these sadācāra. That is secondary. But if one is staunchly devoted to Kṛṣṇa, he is sādhu. Not exactly that he has to observe all the rules and regulations because by practice... Just like these European and American students, sometimes they cannot adopt to the principles of sadācāra, as it is recommended. But that doesn't matter. Because they have devoted, they have sacrificed their life for Kṛṣṇa, they are sādhu. One has to (indistinct). They should be given the respect of a sādhu because they have no other business than Kṛṣṇa. That is recommended from Kṛṣṇa.
