Въгазавад  -гўтаа Аѕ Іт Іѕ
[Ch. 2]
rāja Ambarīṣa, all of the senses must be engaged in Kṛṣṇa consciousness, for that is the correct technique for controlling the mind.
TEXT 68
तस्माद्यस्य महाबाहो निगृहीतानि सर्वशः । इन्द्रियाणीन्द्रियार्थेभ्यस्तस्य प्रज्ञा प्रतिष्ठिता ॥६८॥
tasmād yasya mahā-bāho nigṛhītāni sarvaśaḥ indriyāṇīndriyārthebhyas tasya prajñā pratiṣṭhitā
tasmāt —therefore;  yasya —of one’s;  mahā-bāho —O mighty-armed one;  nigṛhītāni —so curbed down;  sarvaśaḥ —all around;  indriyāṇi —the senses;  indriya-arthebhyaḥ —for the sake of sense objects;  tasya —his;  prajñā —intelligence;  pratiṣṭhitā —fixed.
TRANSLATION
Therefore, O mighty-armed, one whose senses are restrained from their objects is certainly of steady intelligence.
PURPORT
As enemies are curbed by superior force, similarly, the senses can be curbed not by any human endeavor, but only by keeping them engaged in the service of the Lord. One who has understood this—that only by Kṛṣṇa consciousness is one really established in intelligence and that one should practice this art under the guidance of a bona fide spiritual master—is called  sādhaka , or a suitable candidate for liberation.

या निशा सर्वभूतानां तस्यां जागर्ति संयमी । यस्यां जाग्रति भूतानि सा निशा पश्यतो मुनेः॥६९॥
