If worldly pursuits like wealth and family don't bring lasting satisfaction, what is the recommended path to true happiness?

The source material suggests that worldly attachments are ultimately unfulfilling. Chapter 8 states that even if one were to gain the entire earth through God's grace, the mind would remain unsatisfied. The recommended path to lasting fulfillment is to shift one's focus inward and upward. By 'keeping eternal happiness and peace as the goal in the heart,' one should practice 'the worship of God in all beings.' This is described as the 'giver of the highest attainment.' The key is to achieve the experience of this truth through spiritual practice, thereby attaining a wealth that is eternal, unlike the perishable nature of wealth, riches, wife, and son.
