kášášŁáša-bhakta - a devotee of Lord KášášŁáša; niášŁkÄma - actually desireless; ataeva - therefore; ĹÄnta - peaceful; bhukti - of material enjoyment; mukti - of liberation from material activities; siddhi - of perfection in yogic performance; kÄmÄŤ - those who are desirous; sakali - all of them; aĹÄnta - not peaceful.
The devotee of Lord KášášŁáša has no desire other than serving KášášŁáša. Even so-called liberated people are full of desires. Fruitive actors desire better living accommodations, and jĂąÄnÄŤs want to be one with the Supreme. YogÄŤs desire material opulence, yogic perfections and magic. All of these nondevotees are lusty (kÄmÄŤ). Because they desire something, they cannot have peace.
The peace formula is given by KášášŁáša in the Bhagavad-gÄŤtÄ (5.29):
bhoktÄraáš yajĂąa-tapasÄáš sarva-loka-maheĹvaram
suhášdaáš sarva-bhĹŤtÄnÄáš jĂąÄtvÄ mÄáš ĹÄntim ášcchati
One who simply understands that throughout the entire universe KášášŁáša is the supreme enjoyer and beneficiary of all kinds of sacrifices, penances and austerities, which should be performed only to attain His devotional service, that KášášŁáša is the Supreme Being and thus the proprietor of all the material worlds, and that KášášŁáša is the only friend who can actually do good to all living entities (suhášdaáš sarvabhĹŤtÄnÄm) â one who understands these three principles about KášášŁáša immediately becomes desireless (niášŁkÄma) and therefore peaceful. A kášášŁáša-bhakta knows that his friend and protector in all respects is KášášŁáša, who is able to do anything for His devotee. KášášŁáša says, kaunteya pratijÄnÄŤhi na me bhaktaá¸Ľ praášaĹyati: âO son of KuntÄŤ, declare it boldly that My devotee never perishes.â Since KášášŁáša gives this assurance, the devotee lives in KášášŁáša and has no desire for personal benefit. The background for the devotee is the all-good Himself. Why should the devotee aspire for something good for himself? His only business is to please the Supreme by rendering as much service as possible. A kášášŁáša-bhakta has no desire for his own personal benefit. He is completely protected by the Supreme. AvaĹya rakášŁibe kášášŁáša viĹvÄsa pÄlana. Bhaktivinoda ášŹhÄkura says that he is desireless because KášášŁáša will give him protection in all circumstances. It is not that he expects any assistance from KášášŁáša; he simply depends on KášášŁáša just as a child depends on his parents. The child does not know how to expect service from his parents, but he is always protected nevertheless. This is called niášŁkÄma (desirelessness).
Although karmÄŤs, jĂąÄnÄŤs and yogÄŤs fulfill their desires by performing various activities, they are never satisfied. A karmÄŤ may work very hard to acquire a million dollars, but as soon as he gets a million dollars he desires another million. For the karmÄŤs, there is no end of desire. The more the karmÄŤ gets, the more he desires. The jĂąÄnÄŤs cannot be desireless because their intelligence is unsound. They want to merge into the Brahman effulgence, but even though they may be raised to that platform, they cannot be satisfied there. There are many jĂąÄnÄŤs or sannyÄsÄŤs who, after taking sannyÄsa and giving up the world as false, return to the world to engage in politics or philanthropy or to open schools and hospitals. This means that they could not attain the real Brahman (brahma satyam). They have to come down to the material platform to engage in philanthropic activity. Thus they again cultivate desires, and when these desires are exhausted, they desire something different. Therefore the jĂąÄnÄŤ cannot be niášŁkÄma, desireless. Nor can the yogÄŤs be desireless, for they desire yogic perfections in order to exhibit some magical feats and gain popularity. People gather around these yogÄŤs, and the yogÄŤs desire more and more adulation. Because they misuse their mystic power, they fall down again to the material platform. It is not possible for them to become niášŁkÄma, desireless.
The conclusion is that only the devotees, who are simply satisfied in serving the Lord, can actually become desireless. Therefore Caitanya MahÄprabhu says here, kášášŁáša-bhakta niášŁkÄma. Since the kášášŁáša-bhakta, the devotee of KášášŁáša, is satisfied with KášášŁáša, there is no possibility of falldown.
