What is chitta vritti nirodha and how does it define yoga according to Patanjali?
What the words mean
The phrase comes from the Yoga Sutras of Patanjali, an early text on yoga. It is often given as "yogash chitta vritti nirodhah." Each word carries a part of the meaning. Chitta is the mind-stuff, the whole field of thoughts, feelings, and impressions. Vritti means a movement, a wave, or a turning of the mind. Nirodha means stilling, calming, or holding back. Put together, the line says that yoga is the stilling of the movements of the mind.
The idea behind it
The text uses the picture of a restless mind. Thoughts rise and fall like waves on water. When the water is choppy, you cannot see your face in it clearly. When it grows calm and still, the reflection becomes clear. In the same way, the tradition holds that the mind is always moving, and these movements cover up the true self, called purusha, the quiet awareness behind all thought. When the movements settle, that pure self is seen as it really is. So in this view, yoga is not adding anything new. It is letting the mind grow quiet enough to reveal what was always there.
Yoga beyond exercise
In many countries today, the word yoga brings to mind stretching, postures, and exercise. The physical poses, called asanas, are one part of the wider path Patanjali describes, but they are not the whole of it. In the Yoga Sutras, yoga points first to the inner work of calming the mind. The poses and breathing are seen as steps that help steady the body and mind for that deeper stillness. This is why the classical meaning is broader than the popular gym idea of yoga.
Why people return to it
Many people read this line as a simple, clear aim: a quieter mind. Teachers of meditation often point to it when they explain that the goal is not to force thoughts away, but to let them settle. How people understand and practice it still varies a lot, by school, teacher, and tradition. The core idea stays the same across them: yoga, in Patanjali's words, is about the mind growing still.
