The deluding energy, or material nature, can act upon the living beings proportionately in terms of the living beings' falling prey to the deluding attraction of māyā. Moths are captivated by the glaring brightness of light, and thus they become prey to the fire. Similarly, the deluding energy is always captivating the conditioned souls to become prey to the fire of delusion, and the Vedic scriptures warn the conditioned souls not to become prey to delusion but to get rid of it. The Vedas warn us to go not to the darkness of ignorance but to the progressive path of light. The Lord Himself also warns that the deluding power of material energy is too powerful to overcome, but one who completely surrenders unto the Lord can easily do so.
(Srimad Bhagavatam----1:17:24----purport).

Rāvaṇa was made a very powerful man by worshiping Lord Śiva, and he used to offer severed heads to please Lord Śiva. He became so powerful by the grace of Lord Śiva that all the demigods were afraid of him, until he at last challenged the Personality of Godhead Śrī Rāmacandra and thus ruined himself. In other words, all such persons who aspire after gaining some or all of the material objects of enjoyment, or the gross materialistic persons, are on the whole less intelligent, as confirmed in the Bhagavad-gītā (7.20). It is said there that those who are bereft of all good sense, or those whose intelligence is withdrawn by the deluding energy of māyā, aspire to achieve all sorts of material enjoyment in life by pleasing the various demigods, or by advancing in material civilization under the heading of scientific progress. The real problem of life in the material world is to solve the question of birth, death, old age and disease.
(Srimad Bhagavatam----2:3:2-7----purport).

The living entities are the enjoyers of the material ingredients, time, modes, etc., because they want to lord it over the material nature. The Lord is the supreme enjoyer, and the living entities are meant to assist the Lord in His enjoyment and thus participate in the transcendental enjoyment of everyone. The enjoyer and the enjoyed both participate in enjoyment, but, deluded by the illusory energy, the living entities want to become the enjoyer like the Lord, although they are not meant for such enjoyment. The jīvas, the living entities, are mentioned in the Bhagavad-gītā as the Lord's superior nature, or parā prakṛti, and so also it is mentioned in the Viṣṇu Purāṇa.
(Srimad Bhagavatam----2:10:12----purport).

It is said that once Indra, the King of heaven, was cursed by his spiritual master, Bṛhaspati, on account of his misbehavior, and he became a hog on this planet. After many days, when Brahmā wanted to recall him to his heavenly kingdom, Indra, in the form of a hog, forgot everything of his royal position in the heavenly kingdom, and he refused to go back. This is the spell of māyā.
(Srimad Bhagavatam----3:30:5----purport).

Atheists gradually develop a demoniac nature and live in the world like beggars chasing after name, fame, wealth, and so on. Constantly deluded by māyā, they live useless lives. On the other hand, those who are truly dedicated to serving the Supreme Lord are never attacked by such a demoniac mentality. These great souls do not carry the title "Mahātmā" as an appendage.
(Renunciation Through Wisdom).

A pure devotee of the Lord cannot be separated from the lotus feet of the Lord for even a moment. Undoubtedly the Lord is always within the hearts of all living creatures, but they hardly know about it because they are deluded by the illusory material energy. The devotees, however, realize the presence of the Lord, and therefore they can always see the lotus feet of the Lord within their hearts. Such pure devotees of the Lord are as glorious as the Lord; they are, in fact, recommended by the Lord as more worshipable than He Himself. Worship of the devotee is more potent than worship of the Lord. It is therefore the duty of the transcendental students to hear of pure devotees, as explained by similar devotees of the Lord, because one cannot explain about the Lord or His devotee unless one happens to be a pure devotee himself.
(Srimad Bhagavatam----3:13:4----purport).
