The Yoga Sutras of Patanjali are 196 aphorisms — terse, compressed, deliberately difficult. Patanjali wrote them to be memorised and unpacked by a teacher, not read independently. But they have been so influential that every subsequent tradition of yoga and meditation in India stands in their shadow.
The second sutra is the most famous: Yogas chitta vritti nirodhah. Yoga is the cessation of the fluctuations of the mind.
Everything else in the text is commentary on this one line.
Chitta is the mind-stuff — the vast, largely unconscious reservoir of all impressions, memories, desires, and conditioned patterns that constitute individual psychology. Vritti means fluctuation, movement, modification — the waves on the surface of the lake. Nirodhah means cessation, restraint, quieting.
When the waves stop, the lake becomes a mirror. And in that mirror, the Purusha — pure Consciousness — sees itself clearly, rather than seeing a distorted reflection of its own activity.
The eight limbs Patanjali prescribes are not a sequential programme — they are a mutually supporting ecology of practice. Yama and Niyama — ethical foundation. Asana — stability and ease in the body. Pranayama — regulation of breath and life force. Pratyahara — withdrawal of the senses from their objects. Dharana — concentration. Dhyana — meditation. Samadhi — absorption.
When the modifications of the mind are restrained through practice and dispassion, the seer abides in its own nature.
The final three — Dharana, Dhyana, and Samadhi — are collectively called Samyama. In Samyama, the distinction between the meditator, the act of meditation, and the object of meditation dissolves. Subject and object become one. This is the state of Nirbija Samadhi — seedless absorption — in which no impressions remain to generate future birth.
Patanjali also describes the Kleshas — the five afflictions that keep consciousness bound. Avidya — ignorance. Asmita — ego-sense. Raga — attraction. Dvesha — aversion. Abhinivesha — clinging to life. Of these, Avidya is the root. All others grow from the fundamental confusion about what we are.
Remove Avidya. See clearly. Everything else resolves.
The Yoga Sutras do not promise bliss or peak experiences. They promise something far more radical: the end of unnecessary suffering. The recognition of what was always already free.
