There are two kinds of liberated souls-those who are liberated by the favor of the Lord and those who are liberated by their own effort. One who gets liberation by his own effort is called an impersonalist, and he merges in the glaring effulgence of the Lord, the brahmajyoti. But devotees of the Lord who qualify themselves for liberation by devotional service are offered four kinds of liberation, namely salokya (status equal to that of the Lord), samipya (constant association with the Lord), sarsti (opulence equal to that of the Lord) and sarupya (features like those of the Lord).
