CHAPTER VI : MEDITATE AND REALISE
According to certain commentators, the entire Gita is an exposition of the great aphorism (TAT TWAM ASI) "You are that'. This chapter is the transition from the yoga of purification of the aspirant (TWAM) to the Yoga of illumination or revelation of that (TAT).
The question arises as to how to control the mind (which is the main base for Sadhana). As per Lord Krishna, the mind can be completely subdued only by repeated practice of remembering God's name (bringing the mind again and again to the Lord as many times as it goes astray) and through detachment i.e., abandoning all desires for enjoyment of worldly objects
