It is often said that it is the nature of the mind to wander. When mind is bored, it searches for happiness outside because it has become its habit to look for happiness outside. It does not know deeply enough that the happiness is within. The mind needs to be trained not to look outside but to look at the source of happiness. The source is whole and complete and all happiness comes from it. The mind needs to be taught to stay in silence. Whenever, a random useless thought appears in mind, the mind needs to be reminded that happiness is not in the outside objects and the thought needs to be squashed. It is the abidance in silence that will give steady happiness to the mind. Silence does not mean not engaging in any act physically or mentally all the time. Mind should be available to us as and when it is required as a tool. But, the mind should not be allowed to take over to roam aimlessly.

[Bhagavad Gita 6.35]

The above implies that without a doubt the mind is unsteady and is difficult to control, but it can be controlled with practice and dispassion.

Goal setting is also an effective way to steady the mind as it gives direction to the thoughts making them less random. If the mind is agitated due to worry, expectations etc. it needs to be reminder that it is not the doer and that everything is not in its control. While it should continue to make efforts without attachment, it also needs to accept the present situation since the whole universe has conspired to make the present situation a reality.
