Generally a person living in a family becomes overly attached to fruitive activity. In other words, he tries to enjoy the results of his activities. A devotee, however, knows that Krishna is the supreme enjoyer and the supreme proprietor (bhoktaram yajna-tapasam sarva-loka-mahesvaram). Consequently, the devotee does not consider himself the proprietor of any occupation. The devotee always thinks of the Supreme Personality of Godhead as the proprietor; therefore the results of his business are offered to the Supreme Lord. One who thus lives in the material world with his family and children never becomes affected by the contaminations of the material world. This is confirmed in Bhagavad-gita (3.9):
yajnarthat karmano ‘nyatra loko ‘yam karma-bandhanah
tad-artham karma kaunteya mukta-sangah samacara
One who tries to enjoy the results of his activities becomes bound by the results. One who offers the results or profits to the Supreme Personality of Godhead, however, does not become entangled in the results. This is the secret of success. Generally, people take sannyasa to become free from the reactions of fruitive activity. One who does not receive the results of his actions but offers them instead to the Supreme Personality of Godhead certainly remains in a liberated condition. In Bhakti-rasamrta-sindhu, Sri Rupa Gosvami confirms this:
iha yasya harer dasye karmana manasa gira
nikhilasv apy avasthasujivan-muktah sa ucyate
If one engages himself in the service of the Lord through his life, wealth, words, intelligence and everything he possesses, he will always be liberated in any condition. Such a person is called a jivanmukta, one who is liberated during this lifetime. Devoid of Krishna consciousness, those who engage in material activities simply become more entangled in material bondage. They have to suffer and enjoy the actions and reactions of all activity. This Krishna consciousness movement is therefore the greatest boon to humanity because it keeps one always engaged in Krishna’s service. The devotees think of Krishna, act for Krishna, eat for Krishna, sleep for Krishna and work for Krishna. Thus everything is engaged in the service of Krishna. A total life in Krishna consciousness saves one from material contamination. As stated by Bhaktisiddhanta Sarasvati Gosvami Maharaja:
Krishna-bhajane yaha haya anukula visaya baliya tyage taha haya bhula
If one is so expert that he can engage everything or dovetail everything in the service of the Lord, to give up the material world would be a great blunder. One should learn how to dovetail everything in the service of the Lord, for everything is connected to Krishna. That is the real purpose of life and secret of success. As reiterated later in the Third Chapter of Bhagavad-gita (3.19):
tasmad asaktah satatam karyam karma samacara
asakto hy acaran karma param apnoti purusah
“Therefore, without being attached to the fruits of activities, one should act as a matter of duty; for by working without attachment, one attains the Supreme.”
The Third Chapter of Bhagavad-gita specifically considers material activities for the purpose of sense gratification and material activities for the purpose of satisfying the Supreme Lord. The conclusion is that these are not one and the same. Material activities for sense gratification are the cause of material bondage, whereas the very same activities for the satisfaction of Krishna are the cause of liberation. How the same activity can be the cause of bondage and liberation can be explained as follows. One may get indigestion due to eating too many milk preparations–condensed milk, sweet rice, and so on. But even though there is indigestion or diarrhea, another milk preparation–yogurt mixed with black pepper and salt–will immediately cure these maladies. In other words, one milk preparation can cause indigestion and diarrhea, and another milk preparation can cure them.
If one is placed in material opulence due to the special mercy of the Supreme Personality of Godhead, he should not consider that opulence a cause for bondage. When a mature devotee is blessed with material opulence, he does not become affected adversely, for he knows how to employ material opulence in the service of the Lord. There are many such examples in the history of the world. There were kings like Prthu Maharaja, Prahlada Maharaja, Janaka, Dhruva, Vaivasvata Manu and Maharaja Iksvaku. All of these were great kings and were especially favored by the Supreme Personality of Godhead. If a devotee is not mature, the Supreme Lord will take away all his opulence. This principle is stated by the Supreme Personality of Godhead–yasyaham anugrhnami harisye tad-dhanam sanaih: “My first mercy shown to My devotee is to take away all his material opulence.” Material opulence detrimental to devotional service is taken away by the Supreme Lord, whereas a person who is mature in devotional service is given all material facilities.
