SBG 2:38 So fight the battle treating alike pleasure and pain, gain and loss as well as victory and defeat. By doing so, you will not sin.
SBG 3:08 Do the duties prescribed for you because action is better than inaction. Even the maintenance of the body cannot be done without doing work.
SBG 3:09 Work binds people to the material world. Hence O Arjuna, do your work perfectly well as a sacrifice for the Bhagavan, so that you can be free from all bondage and attachment.
SBG 3:20 Even Janaka and other kings attained perfection through action. You should perform action with the view of being of benefit to the people of the world.
SBG 3:25 Just as ignorant people perform actions with attachment to the results, learned people perform work, but without being attached to the world. Their desire, if at all, is only the welfare of the world.
SBG 5:10 One who dedicates all his actions to the Supreme Bhagavan and gives up all attachment to his works, is untouched by sin, just as a lotus leaf is by water.
SBG 5:25 Those whose sins have been destroyed, whose minds are beyond dualities, who are always engaged in working for the welfare of all living beings, achieve liberation and absorption in the Supreme Bhagavan.
SBG 11:33 Therefore, get up and attain glory. Conquer your enemies and enjoy a prosperous kingdom. All these warriors have already been destroyed by Me. You are only an instrument, O Arjuna.
SBG 11:55 O Arjuna, he who is engaged in doing My work and considers Me Supreme, is free from contamination of the mind with previous activities and doubts, he who is free from attachment, he who has no enmity towards any creature and he who is friendly with every living entity, certainly comes to Me.
SBG 18:39 That pleasure which at first and in the end is delusive of the Self, which arises from sleep, indolence and heedlessness is declared to be Tamasic.
