Based on the provided text, what are the underlying principles and scriptural justifications for the act of giving?

The text in Chapter 14 outlines several key principles for giving, rooted in scriptural commands. The Taittiriya Upanishad is cited, emphasizing that giving should always be done with faith, as anything given without faith is not truly received. Beyond faith, giving is also contextualized by social and moral obligations: one should give out of respect for authority like a king's command, adherence to scripture, and even social pressure or 'shame.' Giving is also a tool for maintaining friendships and social customs. Ultimately, the Shruti (Veda) is referenced to establish giving, or Dakshina, as a valid means and technique for those on the path to self-knowledge, whether their goals are worldly or spiritual.
