Based on the provided text, what is the relationship between bondage, liberation, and the 'pure, self-controlled state'?

The text from Chapter 17 presents a profound philosophical concept, stating that where there is bondage, there is also liberation, and vice versa. It advises the seeker to transcend both of these dualistic states and instead remain in a 'pure, self-controlled state.' This is achieved by discarding all ignorance related to happiness or sorrow and acquiring special knowledge (Vijnana). As long as the bodily identification of "me and you" persists, true welfare cannot be seen. Therefore, as Chapter 17 explains, one must discard this ego, look at the true Self, and throw away miserliness to attain this transcendent state beyond the duality of bondage and freedom.
