The living entities that reside in the three planetary systems of the material manifestation are suffering from a dangerous virus called Bhava Roga.
This Bhava Roga virus means that a living entity assumes the false identity of the supreme purusha and tries to lord it over the resources of the material nature. By doing so, he becomes further and further entangled in the complexities of material existence and suffers birth, death, old age and disease. How to detect whether someone has the bhava roga virus? We must look at the symptoms of this disease? The most common sign of the Bhava Roga disease is the loss of taste in terms of hearing the transcendental pastimes of the Lord. Another sign of someone being infected with this disease is the material fever.
Material fever makes the living entity foolish enough to identify with the material body made of flesh, bones, blood and mucus and pursue the senseless sense gratification as the aim of life. Thus one becomes the victim of lust, which can never be satisfied and which burns like fire. No matter how much fuel we supply to the fire, it is never extinguished by such a process. Similarly, no matter how much we try to gratify our senses or subtle mind, they are never satisfied. To the contrary, our desire for sense satisfaction is ever increasing resulting in the so-called material advancement of knowledge where modern politicians simply cry the words of desperation when threatened with the atomic holocaust, which may destroy everyone. Any intelligent person must take careful precaution and protect himself against the infection of bhava roga and socially distance himself from the asat-sanga, unwanted association of karmis, jnanis and yogis and take the spiritual vacc*ne of the bhava-bhakti brought to this world by the greatest philanthropist of mankind of the name Lord Caitanya Mahaprabhu. This spiritual vacc*ine can be injected aurally through the channel of bona fide disciplic succession of bona fide spiritual masters and must be taken under authorized supervision. One cannot come to the bhava bhakti all of a sudden but must first of all search out an authorized sadhana bhakti center, where he learns first of all the practice of our long forgotten relationship with the Supreme Lord Krishna by following the rules and regulations of the scriptures presented by the spiritual master. This va*ccine must be injected through the ear by hearing the transcendental science from an authorized spiritual physician, the spiritual master who is a certified representative of Lord Caitanya.
As Srila Prabhupada writes: "His Divine Grace the spiritual master can kindle the spiritual fire from the wood like living entity by imparting proper spiritual messages injected through the receptive ear. Therefore one is required to approach the proper spiritual master with receptive ears only, and thus divine existence is gradually realized." (SB 1.2.32 purport)
In this way, one gains immunity against the deadly disease of bhava roga even though he might be situated in the contaminated area of the material world. Those who suffer lack of taste for the transcendental topics of the Lord and yet do not take the sankirtana vac*ccine of hearing from the bona fide spiritual master become the dangerous anti-vaxxers, who simply spread misinformation in the form of impersonal philosophy. It is better that such dangerous anti-vaxxer put on a mask over their mouths in the form of mona vrata (the vow of silence) just so that the virus of bhava roga cannot spread any further.
