In this world every individual is helpless in some way or another, and every individual is of use in some way or another. It can happen that a person depends unconsciously upon his friend for his own interest, and even then it will turn out to be a wrong attitude. It cannot bring about fruitful results, for friendship must be built upon a solid foundation, a foundation where there is always a desire to give, to be helpful and serviceable to the friend: no thought of taking, always a thought of giving and keeping back nothing. A real friend holds his life cheap for his friend. The one who considers anything more important, more precious than friendship, has not yet learnt the first lesson of friendship. There is no sacrifice too great, if it is made for a friend. If a sacrifice is not made for a friend, then for whom should one make it? A person would never learn how to make any sacrifice if it were not for a friend.
