How does the concept of a 'Vikshipta-chitta' (distracted mind) explain the futility of possessing spiritual knowledge without first renouncing the desire for its fruits?

Chapter 17 defines a 'Vikshipta-chitta,' or a distracted mind, to illustrate why spiritual knowledge can be hollow without inner purity. A person with such a mind is described as obsessed with worldly objects, bodily ego, and prohibited conduct, making them unable to discern their own spiritual benefit or harm. This state is directly connected to the desire for the fruits of one's actions. The text from Chapter 17 asserts that even if someone is "endowed with the science of Brahman, as long as he is not disgusted with the desire for fruits, that science of Brahman is hollow." This implies that theoretical knowledge is insufficient. Without a pure heart and a genuine renunciation of attachment to outcomes, any attempt to follow a spiritual path is merely a "parade of his pride of knowledge" and a waste of effort.
