45. The Vedas deal with the three Gunas. O Arjuna, be thou free from these three Gunas; free from the pairs of opposites (cold and heat, pleasure and pain); ever steadfast, be thou free from (thoughts of) acquiring or keeping and self-possessed.
46. To the Brahmana, the knower of Truth, all the Vedas are of as little use as a small water-tank is during the time of a flood, when water is everywhere.
47. To work alone thou hast the right, but never to the fruits thereof. Be thou neither actuated by the fruits of action, nor be thou attached to inaction.
48. O Dhananjaya, abandoning attachment and regarding success and failure alike, be steadfast in Yoga and perform thy duties. Evenmindedness is called Yoga.
49. O Dhananjaya, work (with desire for results) is far inferior to work with understanding. Therefore seek refuge in the Yoga of understanding. Wretched indeed are those who work for results.
50. Being possessed with this understanding, one frees one's self even in this life from good and evil. Therefore engage thyself in this Yoga. Skillfulness in action is called Yoga.
51. The wise, possessed with knowledge, abandoning the fruits of their actions, become freed from the fetters of birth and reach that state which is beyond all evil.
52. When thine intellect will cross beyond the mire of delusion, then alone shalt thou attain to indifference regarding things heard and yet to be heard.
53. When thine intellect, tossed by the various conflicting opinions of the Scriptures, will become firmly established in the Self, then thou shalt attain Yoga (Self-realization or union with God).
