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.
Recently, at a medical convention held in New Delhi, our honorable prime minister made the following observation in his speech:
We go in for public health, sanitation, and all kinds of preventive measures rather than wait for people to fall ill and then treat them. Why not apply that principle in the larger sphere and prevent social diseases that, left untreated, we will have to deal with later in a much more difficult form? So when wise men like you gather together, perhaps you might think of the ills and diseases of humanity as a whole that create so many conflicts and troubles and impede human progress.
Factually, whatever problems crop up in the world are caused by the mind. Paṇḍitas have researched the scriptures thoroughly and held many discussions on this topic. If we can follow the example set by the subjects of King Ambarīṣa, who under his guidance concentrated their minds on the lotus feet of Lord Kṛṣṇa, then the mind can be cured of all ills. Any other process will bring upon us the fate described by Prahlāda Mahārāja in the Śrīmad-Bhāgavatam (5.18.12): harāv abhaktasya kuto mahad-guṇāḥ manorathenāsati dhāvato bahiḥ.
