Every sense organ has its territory. The eye is drawn to pleasing sights. The tongue craves certain flavors. The ear seeks pleasant sounds. And within each of these territories, two forces sit waiting: raga, the pull toward what you like, and dvesha, the push away from what you dislike.
These two are the real adversaries on the spiritual path. Raga whispers: I want this. Dvesha shouts: I cannot stand that. Together, they pull a person off center. Krishna does not say eliminate all experience. He says: do not let these two forces control you. Recognize them when they arise. Stay steady.
