The Upanishad in chapter 4 discusses virtues in the context of self-knowledge, and asserts that the six inner enemies of man are anger, covetousness, infatuation, conceit, desire and jealousy. The six waves of inner reminder are hunger, thirst, sorrow, craving, old age and dying, while the six embarrassments, states the text, are race, family, social class (varna), stage in life (ashrama) and favorable circumstances. One overcomes these with Yoga, asserts the text, and by meditating on one's soul, and realizing it being one with Vishnu.
