“स ब्रह्मयोगयुक्तात्मा, सुखमक्षयमश्रुते ।।5/21 ||"
“By engaging in god's meditation yoga with full concentration yogi will attain everlasting happiness"
“ध्यानेनात्मनि पश्यन्ति केचिदात्मानमात्मना। अन्य साड्.ख्येन योगेन कर्मयोगेन चापरे ||13/24 ||"
"Different people establish communion with god by different forms of yoga, some by Dhyan Yoga, others by Jnana Yoga and many by Karma yoga".
Barring a few contradictions and ambiguities, Gita, though a concise and brief treatise, covers almost all aspects of life, ennobling and enlightening instructions with its unique subtlety elaborate and comprehensive. There is Astanga yoga also with all the prescribed eight steps.
1.
Yama:
“अहिंसा सत्यमक्रोधस्त्याग शान्तिपैशुनम् ।।16/2||"
"Nonviolence, truth are essential attributes of a yogi".
"आवृतं ज्ञानमेतेन ज्ञानिनो नित्यवैरिणा। कामरूपेण कौन्तैय दुष्पूरेणानत्वेन च ।।3/39 ||"
Indulgence in sex envelops one's knowledge and is inimical. Here celibacy is advised which is an important yama.
Niyama :
“यः सर्वत्रानभिस्नेहस्तत्तत्प्राप्य शुभाशुभम् ।।2/57 ||"
“There should be equanimity in pleasant and unpleasant things i.e. contentment which is an essential Niyama".
“युक्ताहारविहारस्वय युक्तचेष्टस्य कर्मसु । युक्तस्वन्पावबोधस्य योगो भवर्ति दुःखहा।।6/17 ||"
