Those conditioned souls who identify with this illusory material nature and are proud of it, and who do not care to know about the Supreme Lord, are subjugated by the Lord's illusory potency, who is known variously as Mahā Kālī, Cāṇḍī, and Durgā, and who pierces them with her trident of the threefold miseries. These demoniac jīvas are forced into slavery by the illusory potency—Kālī, or Mahāmāyā. The Bhagavad-gītā, which is the essence of all the Vedic scriptures, was compiled for the deliverance of the conditioned souls. By studying the Gītā carefully, a jīva takes shelter of the Supreme Lord's lotus feet and attains liberation from the merry-go-round of repeated suffering in the material world.
7) The conditioned jīva suffers from the material disease—the miseries of birth, death, old age and disease. When this suffering becomes unbearable, he looks for help. Those who are less intelligent embrace the path of impersonal liberation and undertake severe austerities to achieve their goal. More elevated than these salvationists are the devotees of the Lord, who realize that their eternal nature is to be His servants. They do not try to extinguish this nature but rather practice and preach the eternal process of devotion so they can enter the Lord's eternal spiritual abode. All living entities have a right to practice this eternal process of devotional service.
