According to the scriptures mentioned in chapter 14, what are the different motivations for giving, besides just for spiritual progress?

While giving with faith is considered paramount, Chapter 14 mentions several other motivations for giving, reflecting various social and personal pressures. The Taittiriya Upanishad commands that giving should always be done with faith, as anything given without it is not truly received. However, the text also acknowledges other contexts for giving. A person might give something out of fear of a king's command or a scripture's command. One might also give out of a sense of shame. Furthermore, giving is presented as a crucial part of social conduct, necessary for maintaining friendships and fulfilling obligations during social customs like marriages and other events. This illustrates that the act of giving is woven into the fabric of both spiritual and social life.
