Can you explain the philosophical concept of transcending duality as presented in the teachings?

The teachings in Chapter 17 advise that true spiritual attainment involves transcending duality, which means moving beyond the pairs of opposites that define our worldly experience. The text states, "Where there is liberation, there is bondage; where there is bondage, there is liberation. Transcend both states and remain in your pure, self-controlled state." This is achieved by discarding the ignorance associated with happiness and sorrow and acquiring special knowledge (Vijnana). By ceasing to identify with the body and the ego-driven concepts of 'me and you,' one can stop being fragmented by these conflicts and remain stable in the knowledge of Brahman, which is always near.
