IS PAIN NECESSARY FOR GROWTH?
Of course not.
You can grow endlessly and to the infinite in pure love and bliss.
Pain is a feeling that can be enjoyed, like everything else...
But like everything else, is also a choice.
Is pain necessary for growth?
Only if you believe that living in suffering is growth.
So no... Pain is not necessary, you can achieve everything you achieve with pain utilizing the feeling of love.
You will receive all the same benefits, plus so much more.
So instead of accepting pain as part of your Soul growth, start loving yourself and see how everything goes.
Namaste.
