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. Someone who follows the satanic path and always challenges the Supreme Lord may try to fool the people into thinking he is a mahātmā, but the characteristics of an actual mahātmā are found in the Bhagavad-gītā (BG 9.13):
- mahātmānas tu māṁ pārtha
- daivīṁ prakṛtim āśritāḥ
- bhajanty ananya-manaso
- jñātvā bhūtādim avyayam
O son of Pṛthā, those who are not deluded, the great souls, are under the protection of the divine nature. They are fully engaged in devotional service because they know Me as the Supreme Personality of Godhead, original and inexhaustible.
Real mahātmās do not distract their minds with sense gratification and material desires, but with single-minded resolve they engage in the devotional service of the Supreme Lord. Because they are under the protection of His divine energy, they understand that Lord Kṛṣṇa is the supreme cause of all causes. Such persons alone possess all saintly qualities. Lord Kṛṣṇa's devotees are exceptional personalities, for at all times they are embellished with extraordinary characteristics rarely attained even by the demigods. To usher in the age of peace in this world, the presence such mahātmās is imperative.
