विज्ञानसारथिर्यस्तु मनः प्रग्रहवान्नरः ।

vijñānasārathiryastu manaḥ pragrahavānnaraḥ .
so’dhvanaḥ pāramāpnoti tadviṣṇoḥ paramaṃ padam .. 9..
A man who has discrimination for his charioteer and holds the reins of the mind firmly, reaches the end of the road; and that is the supreme position of Vishnu.
Commentary:
A person who has intelligence as the charioteer, whose mind acts as reins, he reaches the final destination of the path, which is the supreme state of God.
The last quarter of this mantra is borrowed from the Rigveda. It says that the state of Vishnu is beheld by the wise ones as the state of all-pervading ether. The place of Vishnu is not a location or a place. It is spread out like ether or space, like the ocean. A river goes everywhere when it reaches the ocean, and it does not remain localised in one place. Likewise is the soul which enters Vishnupada. The Universal Being is Vishnu. The moment a jiva reaches his destination, he enters Vishnupada. Therefore, the body is to be utilised as a vehicle of action in the movement of the soul to God.
There is nothing wrong with our senses, mind, etc., but they should be directed properly. Evil is that which is misdirected. A thing is not evil in itself, but when it performs another’s function it is evil, just as anything out of place is dirt. So everything should be in its proper place, and yoked properly. The world is a training ground in which the objects and the senses are occasions for mastering our energies so that they get unified through the senses, the mind and the intellect. We look weak because all our energies leak out through the senses. If we conserve our health and concentrate our effort in a single channel, it is called dharana. This will make us powerful; this is yoga. By the control of the senses, the mind and the intellect, the soul becomes fit for God-realisation.
After this description, another aspect is being discussed. How are we to subdue the senses? How is the charioteer to control the horses? What steps are we to take? This difficult effort on the part of the soul is called indriya-samyama or manonigraha. It is summed up in the two following slokas.
Swami Vivekananda Says —
Here is a beautiful figure. Picture the Self to be then rider and this body the chariot, the intellect to be the charioteer, mind the reins, and the senses the horses. He whose horses are well broken, and whose reins are strong and kept well in the hands of the charioteer (the intellect) reaches the goal which is the state of Him, the Omnipresent. But the man whose horses (the senses) are not controlled, nor the reins (the mind) well managed, goes to destruction.[Source]
Control the mind, cut off the senses, then you are a Yogi; after that, all the rest will come. Refuse to hear, to see, to smell, to taste; take away the mental power from the external organs. You continually do it unconsciously as when your mind is absorbed; so you can learn to do it consciously. The mind can put the senses where it pleases. Get rid of the fundamental superstition that we are obliged to act through the body. We are not. Go into your own room and get the Upanishads out of your own Self. You are the greatest book that ever was or ever will be, the infinite depository of all that is. Until the inner teacher opens, all outside teaching is in vain. It must lead to the opening of the book of the heart to have any value.[Source]
