Mental wellbeing is more than the absence of distress. It is the ability to think clearly, feel a full range of emotions without being ruled by them, and recover after setbacks. Sleep, relationships, work and meaning all shape it. When life gets busy or painful, the mind is often the first thing we neglect, even though everything else depends on it.
The Gita treats the mind as something to understand and train. Gita 6.34 admits openly that the mind is restless, turbulent and stubborn, and Gita 6.35 says it can be mastered through practice (abhyasa) and detachment (vairagya). Gita 6.26 advises bringing it back gently each time it wanders. Gita 2.62 shows how constant brooding over an object builds attachment, craving and finally anger, and Gita 6.6 says a mastered mind is a friend while an uncontrolled one is an enemy.
The Gita also gives larger perspective. Gita 2.22 compares death to changing worn-out clothes, offering a way to meet loss with understanding, and Gita 4.39 says faith, sincere effort and mastery of the senses bring knowledge and lasting peace. Gita 6.5 asks each of us to take responsibility for our own upliftment. Notice what your mind keeps dwelling on, build a daily practice, and combine these ideas with professional care when needed, since a counsellor or doctor can help where reflection alone is not enough.
