You are yogi, and they show some gymnastic, that's all. But real yoga system is yoga indriya-saṁyamaḥ, how to control the indriyas, especially the mind. In this way one can become advanced, dhīra. That is yoga system. It is an artificial means to become dhīra, because without becoming dhīra there is no question of advancing in spiritual life. That is not possible.
So this dhīra, who can...? Mahā-bhāga. Mahā-bhāga, very, very great fortunate person. How he becomes dhīra? Ei rūpe brahmāṇḍa bhramite kono bhāgyavān—this mahā-bhāga-kono bhāgyavān jīva, guru-kṛṣṇa-kṛpāya pāya bhakti-latā-bīja (CC Madhya 19.151). By the blessings of guru... If by his great fortune he comes to a real guru, then he gets the opportunity. That is the test. Ei rūpe brahmāṇḍa bhramite kono bhāgyavān. This opportunity is not for everyone. Kono means somebody. So guru-kṛṣṇa. If actually one is trying to be dhīra, Kṛṣṇa is there within every... Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (BG 18.61). And He advises, guru-kṛṣṇa... Kṛṣṇa says, "Now..." Just like Dhruva Mahārāja. Dhruva Mahārāja, out of his sentiment, went to the forest and to see God. His mother said that "Your, this mental condition cannot be relieved because you want to challenge your father to have the kingdom. So I am poor. I am, although your mother, I cannot request your father. So if it is possible, Kṛṣṇa can do it." She was Kṛṣṇa conscious; therefore the child became so nice, Dhruva Mahārāja. A child inherits the quality of mother, boy; and girl inherits the quality of father. That is the general rule. So his mother was devotee, so he'll naturally become a devotee by the advice of the mother. He went to the forest. So..., but he had no spiritual master. Out of sentiment went to the forest. But Kṛṣṇa saw from within that "This child is so serious about Me. Oh, send him Nārada. 'Nārada, you go there. Initiate him.' " Oṁ namo bhagavate vāsudevāya, this mantra was given to Dhruva Mahārāja by Nārada Muni. So he practiced that mantra, and with austerity, and he saw Kṛṣṇa. And when he saw Kṛṣṇa, he's completely pure from all material desires. Anyābhilāṣitā-śūnyam (Brs. 1.1.11). When Kṛṣṇa wanted to give him benediction, he said, svāmin kṛtārtho 'smi varaṁ na yāce: (CC Madhya 22.42) "I am fully satisfied. I don't want anything." This is Kṛṣṇa conscious, dhīra. No more want. Why want? Here it is said that śreyas-kāmā mahā-bhāga sarvāsām aśiṣāṁ patim. Such persons who are dhīra and most fortunate and sees Kṛṣṇa, then what remains to possess? Everything is there. Sarvāsām aśi... All kinds of benedictions are there, all kinds of. That Kṛṣṇa will take care.
So these things are very nice, that one has to become dhīra, and he can become dhīra. Either he was fortunate, or after becoming dhīra he is fortunate. Both ways he is fortunate, mahā-bhāga. And sreyas-kāmāḥ. When one becomes a devotee he does not anymore ask for anything material. Just like Caitanya Mahāprabhu teaches, na dhanaṁ na janaṁ na sundarīṁ kavitāṁ vā jagadīśa kāmaye (Cc. Antya 20.29, Śikṣāṣṭaka 4). This is dhīra. He frankly says that "I don't want riches. I don't want many followers. I don't want nice wife, very beautiful wife." These things are material demands. They are very much fond of worshiping Durgā. Why? Dhanaṁ dehi rūpavati bhāryāṁ dehi yaśo dehi. These are material. But Kṛṣṇa says, "These persons who are asking for material profit from the different demigods, it can be fulfilled. They are fulfilling." But antavat tu phalaṁ teṣāṁ tad bhavati alpa-medhasām (BG 7.23). These material gains, they will stay for a few days or few years. Because you are creating another body.
