श्रेयान्स्वधर्मो विगुणः परधर्मात्स्वनुष्ठितात्।
स्वभावनियतं कर्म कुर्वन्नाप्नोति किल्बिषम्।।18.47।।
।।18.47।। सम्यक् अनुष्ठित परधर्म की अपेक्षा गुणरहित स्वधर्म श्रेष्ठ है। (क्योंकि) स्वभाव से नियत किये गये कर्म को करते हुए मनुष्य पाप को नहीं प्राप्त करता।।
To adhere to ones own natural path of dharma or righteousness is what is being emphasised by Lord Krishna here. It is not as if one must follow the path of another. Everyone is entitled to perform those activities that are appropriate for their rank and station in life in constituting their propitiation to the Supreme Lord; but one must eliminate all sense of doership and desire for rewards. Such karma yoga or actions facilitating communion with the Supreme absolute expressed in visible activities which conform to the inherent nature of the individual manifest easily and naturally. Thus karma yoga performed in this manner is factually ones own path of dharma albeit destitute of merit. By anothers dharma is meant jnana yoga or facilitating communion with the Supreme absolute by knowledge which depending on time and circumstance may or may not be helpful. Perfection in jnana yoga demands the consistent ability to completely control the mind and conquer the senses which is a lifetime endeavour and fraught with danger of lapses in constancy. So karma yoga is more fortuitous as the risks are minimal and chances for succeeding are greater even though jnana yoga is on a superior platform. A jiva or embodied being ensconced in a physical body with an appropriate mind and senses finds it normal to act in accordance with the natural impulses instigated by the senses. This is karma yoga and fulfilling activities in this manner if they do not contradict the injunctions of the Vedic scriptures or disregard the prohibitions thereof incur no sin, for actions speak for themselves. Whereas in jnana yoga once control of the mind and mastery of the senses has been achieved they must be kept controlled and mastered otherwise one will fall down from their position and subjected again to mundane desires and the influence of objects the senses which propels one to sin and locks one in samsara the perpetual cycle of birth and death. So by clearly elucidating the fact that karma yoga is indeed safer and more sure of success, Lord Krishna further corroborates what He previously had promulgated in chapter three.
