In Bhagwat Geeta Lord Shri Krishna talks a lot about controlling your mind.
Like this versesaying from Bhagavad Gita 6.6: “For him who has conquered the mind, the mind is the best of friends; but for one who has failed to do so, his mind will remain the greatest enemy.”
But my question is why God made mind so cunning and hard to control at first place?
Why didn't he designed the mind in the way that it may automatically act to serve the God or stay away from all such wrong doings?
