Kar bhalaa ho bhalaa - Do good and good will come back

There is an old saying in North India -

              कर भला होय भला - अंत भले का भला 
      Kar Bhalaa - hoye Bhalaa
      Ant Bhalay ka Bhalaa

             
Meaning:
Do good - and good will come back to you.
In the end, good always begets good.

Therefore, we should always try to do good - to help others as much as possible - help physically or teach and guide others in any way we can - in whatever capacity we can.
No one can take away from us the ability - our potential, and inclination to do good for others and for ourselves. 

No matter what anyone does to stop us, we can always find a way to share the goodness of our hearts with others.

We lose it only when we give it up ourselves - willingly.
So, never give it up.
Never stop being good or doing good for others.
Because in the end - Good generates Good.
