योगस्थः कुरु कर्माणि सङ्गं त्यक्त्वा धनञ्जय।
सिद्ध्यसिद्ध्योः समो भूत्वा समत्वं योग उच्यते।।2.48।।
2.48 By being established in Yoga, O Dhananjaya (Arjuna), undertake actions, casting off attachment and remaining eipoised in success and failure. Eanimity is called Yoga.
2.48 Abandoning the attachment to kingdom, relatives etc., and established in Yoga, engage in war and such other activities. Perform these with eanimity as regards success and failure resulting from victory etc., which are inherent in them. This eanimity with regard to success and failure is called here by the term Yoga, in the expression established in Yoga. Yoga is eanimity of mind which takes the form of evenness in success and failure. Sri Krsna explains why this is repeatedly said:
Yogasthah kuru karmaani sangam tyaktwaa dhananjaya; Siddhyasiddhyoh samo bhootwaa samatwam yoga uchyate.
