and thereafter;  niyamya —regulating;  etat —this;  ātmani —in the self;  eva —certainly;  vaśam —control;  navet —must bring in.
TRANSLATION
From whatever and wherever the mind wanders due to its flickering and unsteady nature, one must certainly withdraw it and bring it back under the control of the Self.
PURPORT
The nature of the mind is flickering and unsteady. But a self-realized  yogī  has to control the mind; the mind should not control him. One who controls the mind (and therefore the senses as well) is called  gosvāmī , or  svāmī , and one who is controlled by the mind is called  godāsa , or the servant of the senses. A  gosvāmī  knows the standard of sense happiness. In transcendental sense happiness, the senses are engaged in the service of Hṛṣīkeśa or the supreme owner of the senses—Kṛṣṇa. Serving Kṛṣṇa with purified senses is called Kṛṣṇa consciousness. That is the way of bringing the senses under full control. What is more, that is the highest perfection of  yoga  practice.
TEXT 27
प्रशान्तमनसं ह्वेनं योगिनं सुखमुत्तमम् । उपैति शान्तरजसं ब्रह्मभूतमकल्मषम् ॥२७॥
praśānta-manasaṁ hy enaṁ yoginaṁ sukham uttamam upaiti śānta-rajasaṁ brahma-bhūtam akalmaṣam
praśānta —mind fixed on the lotus feet of Kṛṣṇa;  manasam —of one whose mind is so fixed;  hi —certainly;  enam —this;  yoginam —the  yogī ;  sukham —happiness;  uttamam —the highest;  upaiti —attains;  śānta-rajasam —pacified passion;  brahma-bhūtam —liberated by identification with the Absolute;  akalmaṣam —freed from all past sinful reaction.
TRANSLATION
The yogī whose mind is fixed on Me verily attains the highest happiness. By virtue of his identity with Brahman, he is liberated; his mind is peaceful, his passions are quieted, and he is freed from sin.
