This quote is from the Bhagavad Gita, a Hindu scripture. The original verse in Sanskrit is "Ma phaleshu kadachana, ma karmaphalaheturbhuh, ma te sango 'stv akarmani," which can be translated as "Let not the fruits of action be your motive, nor let your attachment be to inaction." This quote emphasizes the importance of focusing on the action itself, rather than being attached to the outcome or being inactive. It suggests that one should perform their duty without worrying about the results, and that inaction is not a solution to any problem. The verse encourages one to engage in action without being attached to the outcome, and to perform their duty to the best of their ability without expecting any particular result. It reminds us that action is necessary in life, and that we should not let our attachment to the outcome or fear of failure prevent us from taking action.
