From Prabhupada's purport to Srimad Bhagavatam Canto 3 Chapter 15 Verse 21"It is also stated here that in the Vaikuṇṭha planets the goddesses of fortune are faultless. Generally the goddess of fortune does not remain steadily in one place. Her name is Cañcalā, which means "one who is not steady." We find, therefore, that a man who is very rich may become the poorest of the poor.
Another example is Rāvaṇa. Rāvaṇa took away Lakṣmī, Sītājī, to his kingdom, and instead of being happy by the grace of Lakṣmī, his family and his kingdom were vanquished. Thus Lakṣmī in the house of Rāvaṇa is Cañcalā, or unsteady. Men of Rāvaṇa's class want Lakṣmī only, without her husband, Nārāyaṇa; therefore they become unsteady due to Lakṣmījī. Materialistic persons find fault on the part of Lakṣmī, but in Vaikuṇṭha Lakṣmījī is fixed in the service of the Lord. In spite of her being the goddess of fortune, she cannot be happy without the grace of the Lord. Even the goddess of fortune needs the Lord's grace in order to be happy, yet in the material world even Brahmā, the highest created being, seeks the favor of Lakṣmī for happiness."
