According to the provided text, what is the deeper spiritual and cultural justification for offering Dakshina during worship?

The text presents Dakshina as a spiritually significant act, not just a monetary gift. Chapter 14 explains that it is the 'golden flower' that distributes the fruit of great wealth. The practice is justified by citing Vedic mantras which state, 'Those who give Dakshina stay in high places; those who give gold become immortal; those who give gold become pure in heart.' This frames the offering as a means to achieve spiritual merit, purity, success, and auspiciousness. The text argues that since Dakshina is approved even for the worship of gods, it is equally appropriate and necessary for the worship of saints to ensure the completion of vows and gifts.
