Maa Phaleshu Kadachana,
Maa Karma Phala Hetur Bhur
Maa Te Sangostva Akarmani”
From the Bhagavad Gita – Chapter 2, Sloka 47
You have the right to perform your actions, but you are not entitled to the fruits of the actions.
Do not let the fruit be the purpose of your actions, and therefore you won’t be attached to not doing your duty.
This sloka has to be divided into four quarters.
1. Karmanye vadhikaraste: you have a right to work only
2. Maa phaleshu kadachana: no right for the fruits thereof.
3. Maa karma phala hetur bhur: let not the fruits be your motive.
4. Maa te sangostva akarmani: let not be attached to inaction.
