Eternal Perfection Persons who have achieved eternal, blissful life exactly on the level of Śrī Kṛṣṇa, and who are able to attract Lord Kṛṣṇa by their transcendental loving service, are called eternally perfect. The technical name is nitya-siddha. There are two classes of living entities—namely, nitya-siddha and nitya-baddha. The distinction is that the nitya-siddhas are eternally Kṛṣṇa conscious without any forgetfulness, whereas the nitya-baddhas, or eternally conditioned souls, are forgetful of their relationship with Kṛṣṇa.
