Sometimes the material world is likened to a dream. Srila Bhaktisiddanta Saraswati Thakur says that just as one soon forgets the experience of a dream after awakening, similarly, a liberated soul in Krsna consciousness does not see anything substantial in even the most exalted rewards offered by the Vedas, such as promotion to the heavenly planets. Therefore Lord Krsna advised Arjuna in Bhagavad-gita to remain fixed in self-realization, without being deviated by fruitive rituals performed in the name of religion.
