BG 2.61
तानि सर्वाणि संयम्य युक्त आसीत मत्परः ।
वशे हि यस्येन्द्रियाणि तस्य प्रज्ञा प्रतिष्ठिता ॥ ६१ ॥
tāni sarvāṇi saṁyamya
yukta āsīta mat-paraḥ
vaśe hi yasyendriyāṇi
tasya prajñā pratiṣṭhitā
tāni — those senses; sarvāṇi — all; saṁyamya—keeping under control; yuktaḥ — being engaged; āsīta — being so situated; mat-paraḥ — in relationship with Me; vaśe — in full subjugation; hi — certainly; yasya — one whose; indriyāṇi — senses; tasya — his; prajñā — consciousness; pratiṣṭhitā — fixed.
One who restrains his senses and fixes his consciousness upon Me is known as a man of steady intelligence.
That the highest conception of yoga perfection is Kṛṣṇa consciousness is clearly explained in this verse. And, unless one is Kṛṣṇa conscious, it is not at all possible to control the senses. As cited above, the great sage Durvāsā Muni picked a quarrel with Mahārāja Ambarīṣa, and Durvāsā Muni unnecessarily became angry out of pride and therefore could not check his senses. On the other hand, the King, although not as powerful a yogī as the sage, but a devotee of the Lord, silently tolerated all the sage's injustices and thereby emerged victorious. The King was able to control his senses because of the following qualifications, as mentioned in the Śrīmad-Bhāgavatam:
The word mat-paraḥ is most significant in this connection. How one can become a mat-paraḥ is described in the life of Mahārāja Ambarīṣa. Śrīla Baladeva Vidyābhūṣaṇa, a great scholar and ācārya in the line of the mat-paraḥ, remarks: "mad-bhakti-prabhāvena sarvendriya-vijaya-pūrvikā svātma dṛṣṭiḥ sulabheti bhāvaḥ." "The senses can be completely controlled only by the strength of devotional service to Kṛṣṇa." Also the example of fire is sometimes given: "As the small flames within burn everything within the room, similarly Lord Viṣṇu, situated in the heart of the yogī, burns up all kinds of impurities." The Yoga-sūtra also prescribes meditation on Viṣṇu, and not meditation on the void. The so-called yogīs who meditate on something which is not the Viṣṇu form simply waste their time in a vain search after some phantasmagoria. We have to be Kṛṣṇa conscious—devoted to the Personality of Godhead. This is the aim of the real yoga.
