Acharya Prashant explains that anger is often considered a pure emotion because it originates directly from the body and can bypass thought, making one act like a pure animal. However, most people experience a calculated and partial anger because of self-interest and fear of consequences. He asserts that only a yogi can experience total anger, like the Tandava of Shri Krishna or Shiva, because a worldly person's emotions are always divided by selfishness. True purity in emotion requires being free from the 'mathematics' of gain and loss.
