मुक्तसङ्गोऽनहंवादी धृत्युत्साहसमन्वितः।
सिद्ध्यसिद्ध्योर्निर्विकारः कर्ता सात्त्विक उच्यते।।18.26।।
।।18.26।।जो कर्ता रागरहित? अनहंवादी? धैर्य और उत्साहयुक्त तथा सिद्धि और असिद्धिमें निर्विकार है? वह सात्त्विक कहा जाता है।
Now Lord Krishna describes the threefold effects of the three gunas or modes of material nature on a performer of activity beginning with sattva guna the mode of goodness. 1) muktah-sangah is free from attachment and exempt from desires for results. 2) anaham-vadi is free from egoism as the doer and hence devoid of pride. 3) dhrti is fortitude and determination in surmounting all odds for accomplishment. 4) utsaha is enthusiasm and zeal in undertaking prescribed Vedic activities. The words siddhy-asiddhyor nirvikarah means equipoise in success or failure of all activities, realising that all results are under the auspices of karma or reactions to actions and the ultimate will of the Supreme Lord. Such consciousness is situated in sattva guna.
