“Knowledge can protect you much better than a strong castle!”

“If you are strong enough, you can enjoy even in the middle of a storm!”

“A fence can protect you from cows but not from tanks! In life, there is no complete shield.”

“You build a thousand castles, a thousand sanctuaries, you are nothing; you build a library, you are everything!”

“Frog in a little pond can be much happier than fish in a vast ocean!”

“Instead of building castles against your enemies, build bridges for them to come to you!”

“Much sooner than we think, comes the end! Science is the only master who can change this.”
