Episode 77 covers the final part of chapter 17. In the first three parts we have seen the influence of the three guNAs, sattva, rajas and tamas on faith we have, food we consume, sacrifices we perform, austerities at the body, speech and mind levels and also charities we give. The final part explains the meaning of the three words OM tat and sat separately and together, and when they are used. This is followed by chapter appreciation which will address two important aspects of this chapter.
