Overthinking feels modern, but the texts describe it with complete familiarity. Arjuna calls the mind harder to restrain than the wind; the Buddha compares it to a fish thrashing on dry land. Whatever we invented in the last century, the racing mind is not it.
The traditions also agree, roughly, on the treatment: not arguing with thoughts (that is just more thinking) but training — repeated, gentle, unglamorous redirection, the way a craftsman trues a shaft or a rider gentles a horse.
The verses
The Blessed Lord said: Undoubtedly, O mighty-armed one, the mind is restless and difficult to control. But it can be restrained through practice (abhyasa) and detachment (vairagya), O son of Kunti.
Krishna concedes Arjuna's complaint — yes, the mind is restless and hard to control — then names the only two tools that work: practice and detachment. Not a trick; a training.
The mind is restless, unsteady, hard to guard, hard to restrain. The wise one straightens it as a fletcher straightens an arrow shaft.
The fletcher straightening an arrow is the Dhammapada's image for working with a restless mind: steady pressure, repeated, in one direction. Nobody straightens an arrow by scolding it.
When troubled by perverse thoughts, cultivate their opposites.
Patanjali's technique for rumination: when harmful thought-loops run, deliberately cultivate the opposite. You do not empty the mind — you give it better work.
How to sit with it
Overthinking cannot be out-thought — every argument you win against your mind is played by your mind. The verses point elsewhere: give attention a home (the breath, a line of scripture, the next small task) and return to it every time you notice the loop. The noticing-and-returning is the practice; each return is one pass of the fletcher's hand.

Frequently asked questions
Which verse helps with overthinking?
Bhagavad Gita 6.35 is the honest one: the mind is hard to control, and practice (abhyasa) plus detachment (vairagya) are what tame it. Dhammapada 3.1 and Yoga Sutra 2.33 give the working methods.
How do you stop rumination according to the Yoga Sutras?
Sutra 2.33 prescribes pratipaksha bhavana — cultivating the opposite: when a corrosive thought-pattern runs, deliberately raise its counter-thought. Attention is redirected rather than suppressed.
