“If somebody insists to be your enemy, you insist more to be his friend!”

“Neither the stone that made you stumble is your enemy, nor the stone that helped you cross the river is your friend! Universe just lives its own life!”

“If you want to be friend of progression, be the enemy of fear!”

“Hate is your enemy; you must defeat it! Anger is your enemy; you must defeat it! Violence is your enemy; you must defeat it! Death is your enemy; you must defeat it! Know well your real enemies!”

“Universe is a friend, it creates us; universe is an enemy, it kills us! It is neither a complete-friend, nor a complete-enemy.”

“When somebody criticise you, be happy and thankful because they have given you an opportunity to think about the matter more precisely and more detailed!”

“When your enemy falls to the ground, help him to get up! Never let a man in that condition stay on the ground! To help the weak, be it enemy, be it rival, is an honour for you!”
