Will I really get the fruit of whatever I do?
You reap what you sow
The Gita and the Ramcharitmanas both say that as you act, so you reap. So think carefully before you act, because the fruit comes to everyone.
The knowledge of the Gita is that as one acts, so is the fruit. It is not just us saying it; the Ramcharitmanas also says in a chaupai: karma is supreme in the world, and as one does, so one reaps.
