Bhagavad Gita



ತಸ್ಮಾದಸಕ್ತಃ ಸತತಂ ಕಾರ್ಯಂ ಕರ್ಮ ಸಮಾಚರ ।
ಅಸಕ್ತೋ ಹ್ಯಾಚರನ್ ಕರ್ಮ ಪರಮಾಪ್ನೋತಿ ಪೂರುಷಃ॥೧೯॥
tasmādasaktaḥ satataṃ kāryaṃ karma samācara |
asakto hyācaran karma paramāpnoti pūruṣaḥ||19||

Gist of the sloka:
Therefore, renouncing the attachments to rewards, perform your duty sincerely. With such actions, one will reach Lord.
Explanation:
With all the reason given, one must perform their duties sincerely. Whatever needs to be done, do it without fail. But, do it after renouncing the rewards, without ego and by offering it as a worship to Lord. When doing your karmas like this, it would take you towards Lord.
Performing, with the renunciation and as a worship of Lord, would never let you back into the karmic cycle. This is the method to perform the karmas and reach the Lord. Instead, by renouncing the karmas, itself one cannot reach the Lord.
The word ‘purusha’ mentioned here, indicates one who is residing in a fully formed body [human body]. One who utilizes this body to the fullest extent [sadhaka purusha] towards karma yoga, is ‘purusha’.
