Zoroaster, one day, asked the Prince of Iran, ‘Go, light this lamp, from yonder flame.’ The lamp could not be lit; for the wick was soaked in water. Then Zoroaster said, ‘Your mind is so soaked in desire that it cannot receive the wisdom it needs; dry it in the sun of detachment.’ When teachers and the taught are immersed in worldly desire, how can light be transmitted or kept alive? (SSS Vol.7, p. 80)
Threefold progress can be seen in the pronouncements of Zoroaster. First, he declared: ‘I am in the light.’ Then he said: ‘The light is in me.’ Finally he declared: ‘I am the light.’ These declarations can be compared to the three systems of Indian philosophy Dualism, Qualified Nondualism and Nondualism.
