To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.
Without strong affection, and humanity of heart, and gratitude to that Being whose code is mercy, and whose great attribute is benevolence to all things that breathe, true happiness can never be attained.
Life without death and happiness without misery are contradiction and neither can be found alone, because each of them is a different manifestation of the same thing.
If Allah has written for you happiness, no one can steal that from you, and if He has written for your heart to break, then no-one can mend it but He, so always put your trust in Allah.
Life at its noblest leaves mere happiness far behind; and indeed cannot endure it. Happiness is not the object of life: life has no object: it is an end in itself; and courage consists in the readiness to sacrifice happiness for an intenser quality of life.
But remember that the pain of parting from friends will be felt by everybody at times, whatever be their education or state. Know your own happiness. You want nothing but patience; or give it a more fascinating name: call it hope.
