From a philosophical standpoint, why is giving a monetary offering like Dakshina considered a valid part of saint worship?

The philosophical justification for offering Dakshina is multifaceted. Chapter 14 explains that it transforms self-interest into a spiritual goal, where wealth leads to religious merit, and merit leads to knowledge. The text draws a parallel to worldly affairs, noting that since all dealings, including compensation for loss of reputation, are based on money, it is a suitable medium for sacred transactions as well. It further argues that if Dakshina is approved for the worship of gods, as referenced in mantras like "Hiranyagarbha-garbhastha," there is no reason it should not be valid in the worship of saints. It is a recognized method for completing devotional acts and receiving spiritual fruits.
