Control your mind by Rishi

 Humans have five basic senses: touch, sight, hearing, smell and taste.

If you can control your senses, You can control your mind. 

Arjuna asks why, and Lord Krishna explains that it is lust - which burns like fire and is never satisfied - that causes us to act as if pushed by some unknown force. Lust comes from contact between the indriyas, or senses, and sense objects. We develop attachment or aversion and then the mind and intelligence become involved in satisfying that lust...and thus they also become contaminated.

Since the senses are where lust begins, it is advised that they be controlled and your question is, "how to do that?" First, it is advised that they be engaged in better activity. Like a child, if we want to keep him/her from doing mischief we can tell the child to sit still but that will not last long. We have to keep the child busy in positive engagement. So Lord Krishna advises that we put the senses to work, doing our prescribed duty, but offering the results to the Lord. Second, engage the senses in worship. Keep them pure by avoiding sinful acts and association. Dedicate your mind and body in the Lord's service; remain fully engaged in your work, which has to be done, and make the results of that work an offering.

According to Swami Sivananda -

“Mind and Indriyas (senses) are one. Indriya is a prolongation of the mind…Mind is a mass of Indriyas. Mind is a higher power than the Indriyas…If you can control mind, you can control the Indriyas…”

Thus by controlling our mind, we can control our senses. But how to control our mind?

The Bhagavad Gita says -

asamshayam mahaabaaho mano durnigraham chalam |
abhyaasena tu kaunteya vairagyena cha grihyate || 6.35 ||

This sloka/verse emphasizes on a two-fold technique. This technique later was mentioned by Patanjali Rishi (the author of Yoga Sutra) too. i.e. Abhyasa and Vairagya. Abhyasa means practice or persistent effort and Vairagya means non-attachment or dispassion. Mind can be controlled by persistent effort and dispassion.

It is a continuous process. You can not master your mind or senses overnight. By regular practice of Abhyasa and Vairagya you can have a control over your mind and senses.
