“Mind always searches some reason to be dissatisfied.”
Desires are similar to wild fire. As much we feed it, it will crave for more. There is no end and sometimes we take wrong decisions to fulfill our desires, because of lust our conscience is covered with dust of Materialistic desires and we cannot distinguish between the right and wrong because we have not trained our mind to control it.
According to the vaishnavism we see conscience,mind,body,senses and soul as a chariot.Vedic Upanishads give a very good analogy of the ‘Chariot with Five Horses’. The chariot stands for the human body. Five Horses represent our Five senses. Mind represent Ropes or the reins. Intelligence represents Charioteer (driver). Person on Chariot represents the Spirit Soul or Jiva.
If the charioteer falls asleep or is not alert, then the reins which are to be controlled by the charioteer will become loose and then the horses will go out of control. This then ends up in the destruction of the chariot and the rider. It is clear from this,that if the intellect(the charioteer) loses its grip over its mind (the reins), the mind runs wherever it wants and allows the five sense organs(the five horses) to go wherever they want to and indulge. Then this brings a destruction to man’s personality. So, our senses are uncontrolled because our intelligence unable to receive proper instructions from Soul.
The mind is the center of all activities and is described here as bṛhad-bala, very powerful. To get out of the clutches of māyā, material existence, one has to control his mind. According to training, the mind is the friend and the enemy of the living entity. If one gets a good manager, his estate is very nicely managed, but if the manager is a thief, his estate is spoiled. Similarly, in his material, conditional existence, the living entity gives power of attorney to his mind. As such, he is liable to be misdirected by his mind into enjoying sense objects.
Our senses of sight, hearing, taste, touch, and smell constantly gather information and send it to the mind. Our mind sorts this information into two categories—agreeable or disagreeable—based on how we see the world and what our goals are. For example, if we see this world as meant for our enjoyment—as we tend to do—our mind will accept those things that give pleasure to our senses and reject anything that goes against that pleasure. But this material world is an endless, unpredictable mix of pleasant and unpleasant circumstances that we can’t control. When we let our mind’s decisions—based on our desire for temporary pleasure—dictate our choices, our happiness isn’t guaranteed at all.
A materially oriented mind can’t lead us to permanent fulfillment. For that, we need to train the mind to make judgments based on a more elevated worldview. The system of yoga, as Krishna explains in the Bhagavad-gita, is meant to make our life peaceful by giving our mind a superior objective—specifically, meditating on the Supreme Person. When the mind is controlled in this way, it can be our best friend and help lead us to genuine happiness. Then we can be undisturbed by the temporary comings and goings of pleasure and pain in this world.
The mind is not to be killed. Mind or desire cannot be stopped, but to develop a desire to function for spiritual realization, the quality of engagement by the mind has to be changed. The mind is the pivot of the active sense organs, and as such if the quality of thinking, feeling and willing is changed, naturally the quality of actions by the instrumental senses will also change.
