Extravagance has three forms.

• One is caused by ignorance: a simple man who does not know the value of money spends his pearls for pebbles.
• Another form of extravagance is when a man who is in charge of another person's money spends it without any qualms; he thinks that anyhow it is not his property.
• The third form of extravagance occurs when a man has no control over his will and is attracted by anything that appeals to his weakness; he then spends more than he should. But the one who is master over his will, who is a lover of beauty and generous of heart, even if he spent his last penny for his ideal he cannot be called extravagant, for he is the master. He who is not able to spend what he possesses is the servant of his wealth; he does not know life.
