Patañjali (पतञ्जलि)'s Yoga (योग) Sūtras (सूत्र)
Executive summary
Patañjali (पतञ्जलि)'s Yoga Sūtra (सूत्र) is one hundred and ninety-five lines in four pādas (पाद). Yoga is the stilling of the activities of the mind. Then the seer abides in its own form. Otherwise the seer takes the form of those activities. Practice and dispassion are the two means. The book then names the afflictions, the eight limbs, the powers that come from collecting the mind, and the aloneness that remains when even those powers are set down. A reading the sūtra (सूत्र) itself does not spell, when a sitting uses one, is Vyāsa (व्यास)'s bhāṣya (भाष्य), and the sitting says so.
नेपालीमा
पतञ्जलिको योगसूत्र चार पादमा एक सय पन्चानब्बे पङ्क्ति हुन्। योग चित्तका वृत्तिको निरोध हो। तब द्रष्टा आफ्नै स्वरूपमा रहन्छ। नत्र द्रष्टा ती वृत्तिकै रूप लिन्छ। अभ्यास र वैराग्य दुई साधन हुन्। अनि पुस्तकले क्लेश, आठ अङ्ग, मन जम्मा हुँदा आउने शक्ति, र ती शक्ति पनि छाड्दा रहने कैवल्य भन्छ। सूत्रले आफैँ नखोलेको पढाइ बैठकले प्रयोग गर्दा त्यो व्यासको भाष्य हो, र बैठकले त्यही कुरा भन्छ।
The four pādas
One sūtra is one sitting. The line is read in Sanskrit, then split into words, then put back together as phrases. The grammar is the ending that line needs. This is the same kind of book as Learn Sanskrit, not a music room.
The first sixteen name yoga (योग), the five activities of the mind, and the two means of stilling them. Stay with them until citta (चित्त), vṛtti (वृत्ति), nirodha (निरोध), draṣṭṛ (द्रष्टृ), abhyāsa (अभ्यास), and vairāgya (वैराग्य) come without looking. The list of those words sits at the end of 1.16.
The path of every line, Sanskrit and one sentence, is all 195 lines.
When a sitting gives a reading the sūtra (सूत्र) itself does not spell, the reading is Vyāsa (व्यास)'s bhāṣya (भाष्य), the primary commentary. The sitting names him there. The line you recite is still the sūtra (सूत्र). The grammar is worked from the ending.
