In plain words
Hardship and happiness, the two, are joined together; no one has the power to part them; happiness we never see anywhere on its own; when hardship bears fruit, they call it happiness.
Where has happiness come from? Happiness comes only when sorrow and hardship are overcome. The young men and women of today are becoming slaves to this happiness. The whole prosperity of the country rests on them. Men go through many kinds of experience in many kinds of states. In the waking state man goes through many kinds of experience. In the same way, in the states of dream he creates for himself, by himself. Not only that: he himself fashions his own hardships and happiness. He himself fashions the experience of truth and lives through it. In the state of sleep he forgets himself and experiences Ānanda. Waking, dream and deep sleep: all three are the experiences of one and the same person. So man's experiences come to him as the moment brings them. Man's victories and defeats, hardships and losses, happiness and sorrow: all of them are lived through in keeping with time. Of God they say, ‘Siddhasvarūpāya namaḥ’. That is, because He is the One who brings man's wishes to fulfilment, He was called Siddhasvarūpa. In this same sense He is called Amogha. Mogha means what is limited. Amogha means what is manifold. So God's resolves are amogha; they are endless. Because they are beyond measure, He is also called ‘Apramāṇāya namaḥ’. Whatever happens to us, we must regard all of it as God's will. We must regard happiness and sorrow alike as God's prasāda. In that alone lies our joy. But when defeat, hardship or loss comes upon us for a while, we suffer sorrow. In the world no effect is to be seen without a cause. If you are to eat food, hunger must come. If you are to drink water, thirst must come. If you are to enjoy happiness, some hardships must come. When man is to experience Ānanda without a break, he must experience a little gladness.
