Arurukshoh  muneh yogam karma karanam uchyate I

Yoga arudasya tasya va shamah karanam uchyate II sloka 3

अरुरुक्षोः मुनेः योगं कर्म कारणम् उच्यते ।

योग अरुढस्य तस्य वा शमः कारणम् उच्यते ।। श्लोक ३

Karma is said to be the means of the muni who seeks to attain to yoga; serenity is said to be the means when he has attained to yoga.

He is a muni in the making who applies himself ardently to the practice of meditation. Though practising regularly. his mind does not get concentrated. It wanders away in spite of himself. In that case the yogi ought to engage himself eagerly in karma yoga. The non-yogi who busies himself with the work he undertakes, is rewarded by nature with sound sleep at night. The yogi is busier definitely in the discharge of his duty, but with attachment and selfish motive. Good concentrated meditation is the reward he gets for his disinterested work. He can know thhis fact by experience day by day. Clarity of mind is the result of deep meditation. It is this clarity that gets itself settle as serenity. Through proper meditation the mind gets poised in equilibrium. As the crystallization of a stuff takes place  in a restful condition, so the mind gets fixed in equilibrium through meditation. On the attainment of serenity it becomes fit for all purposes - personal and public. Deep meditation is the yogi's personal activity in which he delights inn the sublimity of the self. At other times the external work that he carries on is done to perfection. Serenity is the sure means for his attaining all these excellences. 

Seernity is the foremost of all the accomplishments of the yogi. From this divine gift emanate merits like unison, equality, truthfulness, good conduct, steadfastness, straightforwardness, non-injury to beings and detachment from the world. 

What are the marks of the yogi who has attained perfection in yoga? The explanation is given in the next sloka
