So this is brahminical qualification, to practice how to fix up the mind at the lotus feet of Kṛṣṇa, and that is the perfection of yoga. Yoga means not to show some magical feats. No. Real perfection of yoga means to fix up the mind at the lotus feet of Kṛṣṇa. Therefore in the Bhagavad-gītā you will find the last conclusion of this yoga chapter, Sixth Chapter,
- yoginām api sarveṣāṁ
- mad-gatenāntar-ātmanā
- śraddhāvān bhajate yo māṁ
- sa me yuktatamo mataḥ
- (BG 6.47)
That was encouraging to Arjuna because Arjuna thought, "Then I am useless. I cannot fix up." But his mind was already fixed up. Therefore Kṛṣṇa encouraged him, "Don't be discouraged. Anyone whose mind is already fixed up in Me always, he is the first-class, topmost yogi." Therefore we should be always thinking of Kṛṣṇa. That is Hare Kṛṣṇa mantra. If you chant Hare Kṛṣṇa, Hare Kṛṣṇa, that means your mind is fixed up in Kṛṣṇa. That is the perfection of yoga. So to become a brāhmaṇa, this is the first qualification, to keep the mind fixed up, not being agitated, śama. And when your mind is fixed up, then your senses will be controlled. If you fix up your mind that "I shall simply chant Hare Kṛṣṇa and take prasādam, no more business," then the senses will be controlled automatically
