In Bhagavad-gita (18.7-8) the Supreme Personality of Godhead explains:
"Prescribed duties should never be renounced. If, by illusion, one gives up his prescribed duties, such renunciation is said to be in the mode of ignorance.
"Anyone who gives up prescribed duties as troublesome, or out of fear, is said to be in the mode of passion. Such action never leads to the elevation of renunciation."
In Srimad Bhagavatam (11.12.1) the Supreme Personality of Godhead explains:
"My dear Uddhava, by associating with My pure devotees one can destroy one's attachment for all objects of material sense gratification. Such purifying associating brings Me under the control of My devotee. One may perform the astanga-yoga system, engage in philosophical analysis of the elements of material nature, practice non violence and other principles of ordinary piety, chant the Vedas, perform penances, take to the renounced order of life, execute sacrificial performances and dig wells, plant trees and perform other public welfare activities, give in charity, carry out severe vows, worship the demigods, chant confidential mantras, visit holy places, or accept major and minor disciplinary injunctions, but even by performing such activities one does not bring Me under his control."
In Bhagavad-gita (18.9 and 18.11) the Supreme Personality of Godhead again explains:
"But he who performs his prescribed duty only because it ought to be done, and renounces all attachment to the fruit, his renunciation is of the nature of goodness, O Arjuna."
"It is indeed impossible for an embodied being to give up all activities. Therefore it is said that he who renounces the fruits of action is one who has truly renounced."

You are your body, right? You are chemical in essence ... right? At least, that’s what one of America’s most influential scientists claims:
I am a collection of water, calcium and organic molecules called Carl Sagan. You are a collection of almost identical molecules with a different collective label.*
Like Sagan, most people believe that they are their body. So if you ask them who they are, they think and respond in terms of bodily labels.
“I’m Susan. I’m blond, 29 years old, a mother, and still 36-24-36!”
“I’m Henry. I’m a white American male and proud of it!”
“I’m John. I’m a lawyer. I’m 40 years old and getting older every day.”
“I’m Alice. I’m a female student. I’m fat and I’m a Methodist.”
Name, race, age, sex, religion, nationality, occupation, height, weight, and so on—all these are bodily labels. Therefore if you consider your body to be yourself, you automatically identify yourself with such labels. If your body is fat and ugly, you think, “Woe is me! I am fat and ugly.” If your body is 60 years old and female, you think, ”I am a 60-year-old female.” If your body is black and beautiful, you think, “I am black and beautiful.”
But is the body really the self? Are you really your body?

In Bhagavad-gita (4.20-21) the Supreme Personality of Godhead again explains:
"Abandoning all attachment to the results of his activities, ever satisfied and independent, he performs no fruitive action, although engaged in all kinds of undertakings.
"Such a man of understanding acts with mind and intelligence perfectly controlled, gives up all sense of proprietorship over his possessions, and acts only for the bare necessities of life. Thus working, he is not affected by sinful reactions."
In Bhagavad-gita (6.17 and 18), the Supreme Personality of Godhead again explains:
"He who is temperate in his habits of eating, sleeping, working, and recreation can mitigate all material pains by practicing the yoga system.
"When the yogi, by practice of yoga, disciplines his mental activities and becomes situated in transcendental, devoid of all material desires, he is said to have attained yoga."
In Srimad Bhagavatam (1.2.8-10) Srila Suta Gosvami explains:
"The occupational activities a man performs according to his own position are only so much useless labour if they do not provoke attraction for the message of the Personality of Godhead.
"All occupational engagements are certainly meant for ultimate liberation. They should never be performed for material gain. Furthermore, according to sages, one who is engaged in the ultimate occupational service should never use material gain to cultivate sense gratification.
"Life's desires should never be directed toward sense gratification. One should desire only a healthy life, or self-preservation, since a human being is meant for inquiry about the Absolute Truth. Nothing else should be the goal of one's works."
In Bhakti-rasamrta-sindhu (1.2.255) Srila Rupa Gosvami explains:
"When one is not attached to anything but at the same time accepts anything in relation to Krsna, one is rightly situated above possessiveness. On the other hand, one who rejects everything without knowledge of its relationship to Krsna is not as complete in his renunciation."
