Parasya saktir vividhaiva sruyate. The Supreme Lord has multi-potencies, which the Lord bestows on His fortunate devotees. The Lord has a special potency by which He spreads the Krsna consciousness movement. This is also explained in Caitanya-caritamrta (Antya 7.11). Krsna-sakti vina nahe tara pravartana: "One cannot spread the holy name of Krsna without being specifically empowered by Lord Krsna." A devotee who receives this power from the Lord must be considered very fortunate. The Krsna consciousness movement is spreading to enlighten people about their real position, their original relationship with Krsna. One requires Krsna's special power in order to be able to do this. People forget their relationship with Krsna and work under the spell of maya life after life, transmigrating from one body to another. This is the process of material existence. The Supreme Lord Sri Krsna personally descends to teach people that their position in the material world is a mistaken one. The Lord again comes as Sri Caitanya Mahaprabhu to induce people to take to Krsna consciousness. The Lord also empowers a special devotee to teach people their constitutional position.
