Every person has both a bad heart and a good heart. No matter how good a man seems, he has some evil. No matter how bad a man seems, there is some good about him. No man is perfect.
So long as we believe in our heart of hearts that our capacity is limited and we grow anxious and unhappy, we are lacking in faith. One who truly trusts in God has no right to be anxious about anything.
The mode of living which is founded upon a total harmlessness towards all creatures upon a minimum of such harm is the highest morality.
If you do the right thing, eventually you will inspire others to do the right thing.
If a householder moulds himself according to the circumstances - just like nature moulds itself according to seasons - and performs his karma, then only shall he acquire happiness. One who does this successfully gains in all walks of life.
