The test of friendship is assistance in adversity, and that too, unconditional assistance, Co-operation which needs consideration is as a commercial contract and not friendship. Conditional co-operation is like adulterated cement which does not bind.
Mahatma GandhiIt is easy enough to be friendly to one's friends. But to befriend the one who regards himself as your enemy is the quintessence of true religion. The other is mere business.
Mahatma Gandhi
