The nature of fruitful activity.
How can the spiritual soul related to the material body develop pure transcendental knowledge?
Krishna, God, the Supreme Person says:
Sheltering fully in Me, with the mind carefully set in the devotional service of the Lord as I have stated it, one must live without personal desire and practice the social and professional system (abide in the social class that characterizes us, whose qualities we have developed).
A purified soul must see that, because the conditioned souls who devote themselves to the satisfaction of the senses have falsely accepted the objects of sensory pleasure as being the truth, all their efforts are doomed. One who sleeps can see many objects of sensory satisfaction in a dream, but such pleasurable things are only the creations of the mind and therefore are ultimately unnecessary. Likewise, the living entity asleep to its spiritual identity also sees many sense objects, but these innumerable objects of temporary pleasure are the creations of the illusory power of the Lord and have no permanent existence. He who meditates on them, urged by the senses, unnecessarily engages his intelligence.
He who has fixed Me in his mind as the goal of life must abandon activities based on the pleasure of the senses and must instead perform a regulated work by the regulatory principles of spiritual upliftment. However, when one is fully engaged in the search for the ultimate truth of the soul, one should not accept the scriptural injunctions governing fruitful activities. Whoever has accepted Me as the supreme goal of life must strictly observe the scriptural injunctions prohibiting sinful activities and, as far as possible, perform the injunctions prescribing minor regulatory duties such as cleanliness and purity. Ultimately, however, one must approach a genuine spiritual master who has full knowledge of Me as I am, who is peaceful, and who, through spiritual upliftment, is no different from Me.
The servant or the disciple of the spiritual master must be free from false prestige, never considering himself as the doer. He should be active and never be lazy and give up all sense of ownership over sense objects including his wife, children, home and society. He should be endowed with feelings of loving friendship towards the spiritual master and should never be sidetracked or disoriented. The servant or disciple should always desire elevation in spiritual understanding, he should not envy anyone and should always avoid unnecessary conversations.
One should see his true self-interest in life in all circumstances and one should remain detached his wife, his children, his house, his land, his family, his friends, his wealth,
