When a person performs Vedic rituals and sacrifices, he does so to elevate himself to the heavenly planets. No one can become qualified to go back home, back to Godhead, by means of such sacrifices. But the Lord is so kind that He accepts a little insignificant service, and therefore it is stated in the Visnu Purana that by following the principles of varnasrama-dharma one can satisfy the Supreme Lord. When the Lord is satisfied, the performer of sacrifices is elevated to the platform of devotional service. Prthu Maharaja therefore expected that his insignificant service to the Lord would be accepted by Him as being greater than that of Laksmiji. The goddess of fortune is called cancala (restless) because she is very restless and is always coming and going. So Prthu Maharaja indicated that even though she might go away out of anger, there would be no harm for Lord Visnu, because He is self-sufficient and can do anything and everything without the help of Laksmiji. For example, when Garbhodakasayi Visnu begot Lord Brahma from His navel, He did not take any help from Laksmi, who was just sitting by Him and massaging His lotus feet. Generally if a son is to be begotten, the husband impregnates the wife, and in due course of time the son is born. But in the case of Lord Brahmas birth, Garbhodakasayi Visnu did not impregnate Laksmiji. Being self-sufficient, the Lord begot Brahma from His own navel. Therefore, Prthu Maharaja was confident that even if the goddess of fortune became angry with him there would be no harm, neither to the Lord nor to himself.
