The inner voice of ego continues: 'I am wealthy. I come from a great family. Who is my equal?' This is the pride of possessions and pedigree — the assumption that wealth and lineage make a person superior. It is the voice of someone who has confused their bank balance with their worth.
Then a curious twist: 'I shall perform yajnas, I shall give charity, I shall celebrate.' On the surface, these sound like good acts. But Krishna immediately labels them ajnanavimohitah — deluded by ignorance. The yajna is for show. The charity is to impress. The celebration is self-congratulation. The outer form is religious; the inner motive is vanity.
This is perhaps the most subtle warning in the chapter. A person can perform every religious ritual and still be firmly in the demonic category — if the driving force is ego rather than devotion. The act matters, but the intention behind it matters more.
