1. The defect of demigod worship

    The most defective part of worshiping demigods is that it creates a definite conception of pantheism, ending disastrously in many religious sects detrimental to the progress of the principles of the Bhagavatam, which alone can give the accurate direction for self-realization in eternal relation with the Personality of Godhead by devotional service in transcendental love.
