How to control an overthinking mind and anxiety according to Bhagavad Gita?

The Bhagavad-gītā acknowledges with profound compassion that the mind is indeed restless, turbulent, obstinate, and very strong, making its subdual more difficult than controlling the wind (BG 6.34). Yet, Lord Kṛṣṇa does not leave us in despair; He clearly states that curbing this restless mind is possible through suitable practice and detachment (BG 6.35). This means that anxiety and overthinking arise from the mind's natural tendency to wander due to its flickering and unsteady nature, but we are not helpless victims of this condition—rather, we are empowered to engage in disciplined spiritual practice that gradually stabilizes our consciousness. The practical method prescribed is to vigilantly watch the mind's movements and, whenever it strays, firmly withdraw it and bring it back under the control of the Self (BG 6.26). This requires consistent practice (abhyāsa) of staying anchored in the present moment through remembrance of the Divine, coupled with detachment (vairāgya) from the temporary anxieties of material existence. By regularly redirecting our attention away from futile mental speculation and toward the Supreme, we cultivate a higher consciousness wherein the mind becomes an instrument of spiritual realization rather than a source of distress, ultimately experiencing inner peace that transcends worldly agitation.
