Sage Patanjali compiled the entire knowledge of yoga into simple easy-to-understand sutras or aphorisms around the 4th century BC. There are total of 196 sutras that clearly gives the techniques for the common man to realise himself and achieve oneness or consciousness. Yoga is one of the darshanas of Shatdarshanas or the 6 different ways of viewing the reality of life under the Indian thought system. It is one of the surest, easiest and most effective paths to self-realisation for anyone.
Sutra in Sanskrit means "Thread". It refers to a concise statement that weaves together ideas, insights, or principles. The verses were strung together like beads on a string. It made it easy to be transmitted from one generation to the next orally without diluting or distorting. The short verses meant, the need of a teacher or a guru to decipher it.
These sutras were divided into 4 different chapters.
1. Samadhi Pada - The path to achieve oneness
2. Sadhana Pada - The practise of yoga
3. Vidbuthi Pada - Manifestation of powers
4. Kaivalya Pada - Liberation
Here is a glimpse of the ten most popular sutras:
The first sutra from chapter 1, verse 1 - 1.1, says:
1.Atha Yoganushasanam - 1.1
Meaning, Now the yoga is explained, or now the discipline of yoga begins.
2. Yoga Chitta Vritti Nirodhaha - 1.2
This is the most important sutra in the entire book. It explains what yoga means. It says yoga is chitta (Mind) vritti (the working or the agitations or the thoughts and the impressions) nirodhaha (destroys).
So yoga means stopping the working of the mind. OR achieving stillness, silence. Destroying or dissolving the mind.
3. Abhyasa Vairagyabhyam Tan-Nirodhah - 1.12
This sutra says that the fluctuations of the mind can be controlled through practice (abhyasa) and non-attachment (Vairagya). Abhyam(together) Tan(their) Nirodhah(stop, control)
Practice and dispassion stop the modifications of the mind.
