Although the demigods are in charge of maintaining different aspects of the universe, Gajendra thought that they were unable to rescue him. Hariṁ vinā naiva mṛtiṁ taranti: no one can rescue anyone from the dangers of birth, death, old age and disease. It is only the Supreme Personality of Godhead who can rescue one from the dangers of material existence. Therefore an intelligent person, to get free from this dangerous existence, approaches the Supreme Personality of Godhead, not any demigod. As confirmed in Bhagavad-gītā (7.20), kāmais tais tair hṛta jñānāḥ prapadyante 'nya-devatāḥ: those who are unintelligent approach the various demigods for temporary material benefits. Actually, however, these demigods cannot rescue the living entity from the dangers of material existence. Like other living entities, the demigods are merely external parts of the Supreme Personality of Godhead's transcendental body. As stated in the Vedic mantras, sa ātma-aṅgāny anyā devatāḥ. Within the body is the ātmā, the soul, whereas the various parts of the body like the hands and legs are external. Similarly, the ātmā of the entire cosmic manifestation is Nārāyaṇa, Lord Viṣṇu, and all the demigods, human beings and other living entities are parts of His body.
