Kṛṣṇa said that "This yoga system, first of all I explained to the sun-god, and he explained to his son, Manu, and Manu explained to his son, Iṣkvāku. In this way, by the paramparā system, by the disciplic succession, the knowledge is coming." Sa kāleneha yogo naṣṭaḥ parantapa. But as soon as it began to be explained to others, without being in the disciplic succession, in the chain of disciplic succession, speaking the same truth, it becomes broken. Sa kāleneha yogo naṣṭaḥ. Yoga naṣṭaḥ. It is spoiled. If one does not come in the disciplic succession, he'll spoil the teaching. That is being done. So-called commentator, teacher of Bhagavad-gītā, he does not come in the disciplic succession. He is self-made guru. Therefore he's not guru. Self-made guru cannot be guru. He must be authorized by the bona fide guru. Then he's guru. This is the fact. Here... Nobody can be self-made anything. A medical practitioner, he cannot become self-made, that "I have studied all the medical books in my home." No. "Have you ever gone to the medical college and taken instruction from the bona fide teachers?" Then, if you have got the certificate, then you are medical practitioner. Similarly, bona fide guru means he must be authorized by the superior guru. Just like Caitanya Mahāprabhu says, āmāra ājñāya guru hañā tāra' ei deśa (CC Madhya 7.128). He must receive the order from the superior. And the superior must be bona fide. Then he's bona fide, not self-made. Tasmād guruṁ prapadyeta jijñāsuḥ śreya uttamam (SB 11.3.21). The direction is that one must go to a guru. But who is guru? Śābde ca pare ca niṣṇātaṁ brahmaṇy upaśamāśrayam. These are the descriptions.
So to find out a bona fide guru is not difficult, provided one is bona fide to search out a guru. Therefore Caitanya Mahāprabhu said, guru-kṛṣṇa-kṛpāya pāya bhakti-latā-bīja (CC Madhya 19.151). By the mercy of guru and Kṛṣṇa... Because by the mercy of Kṛṣṇa one gets a bona fide guru, and by the mercy of bona fide guru, one gets Kṛṣṇa. This is the process. When I am actually serious to have connection with Kṛṣṇa, Kṛṣṇa is sitting in everyone's heart. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe 'rjuna tiṣṭhati (BG 18.61). So Kṛṣṇa can understand. We cannot hide anything from Kṛṣṇa. That is not possible. Because Kṛṣṇa is sitting side by side, just like two birds, sitting side by side. One bird is eating the fruit of the tree. Another bird is the witness. That is the Vedic version. So as soon as I become serious to know about Kṛṣṇa, Kṛṣṇa can understand, "Now My friend is very serious." So He will find out a bona fide guru for him. Therefore Caitanya Mahāprabhu says that guru-kṛṣṇa-kṛpāya pāya bhakti-latā-bīja (CC Madhya 19.151). By the, by the double mercy... Kṛṣṇa's mercy, and guru's mercy. If one is serious, Kṛṣṇa is satisfied: "Now he's serious about finding out, about knowing Me." Then Kṛṣṇa gives him direction that "Here is guru, My representative. You take shelter of him and you will get Me." This is the way.
That is explained in this..., that by the grace of Kṛṣṇa, that it is a fortunate person. Fortunate person means he must be sincere, serious to know about Kṛṣṇa. That is fortunate. Because our misfortune has begun by forgetting Kṛṣṇa. Kṛṣṇa bhuliya jīva bhoga vāñchā kare. When we desire to enjoy this material world, forgetting service of Kṛṣṇa, that is the beginning of our misfortune. That is the beginning. Because as soon as I forget Kṛṣṇa, that is the beginning of my misfortune. So in order to be, in order to become again fortunate, I have to become Kṛṣṇa conscious. That is the way. The same... By some way or other... Anādi-bahirmukha jīva kṛṣṇa bhuli gela ataeva kṛṣṇa māyā..., ataeva māyā tāre galila baddhiya (?). Some way or other, we forgot Kṛṣṇa. Unfortunate because we are, even we have got this opportunity of remembering Kṛṣṇa, we are trying to avoid Him. We are bringing so many nonsense things: "Why not this? Why not that? Why not...?" This is misfortune. Kṛṣṇa says, sarva-dharmān parityaja mām ekaṁ śaraṇaṁ vraja. But we are presenting, "Why not this? Why not that? Why not this? Why not that?" this is our misfortune. Why? Kṛṣṇa says, mām ekam. Why shall I try to put another alternative? Why? What is the reason? That is our misfortune. Kṛṣṇa is offering the fortune. Sarva-dharmān parityaja mām ekaṁ śaraṇaṁ vraja. This is fortune. But I'll not take that. Kṛṣṇa says, "Get up. Give up all other engagements. Simply take shelter of Me. I shall give you all protection." But I don't believe Kṛṣṇa; therefore it is my misfortune. This fortune, to become fortunate and misfortunate... Just like in English word, "Man is the architect of his own fortune." Is it not? "Man is the architect of his own fortune." But if you, as you are architect of your own fortune, you are architect of your own misfortune also. So if you don't accept Kṛṣṇa's advice, then you must consider yourself unfortunate. We should be cautious: "Why shall I become unfortunate? I must become fortunate." So that, to become fortunate, is not very difficult thing. All these Kṛṣṇa consciousness people, they are fortunate. They have taken Kṛṣṇa's advice as it is, without any change. They're fortunate. And that is being manifested, that they are fortunate.
