Arjuna has just been told about Self-knowledge; now he asks a very practical question: when a person attains this knowledge, how does it show? How do such people conduct themselves in everyday life? We expect a list of virtues. Instead, Krishna delivers a surprise: the surest sign is that they have banished all selfish desires. Their senses and mind are completely trained, so they are free from sensory cravings and self-will. Identified completely with the Self, not with body or mind, they realize their immortality here on earth.
