What's the real " tawakkul" (trust in Allah SWT)

Assalaam Alaikum Wa Rahmatullahi Wa Barakatuh,

Scholar Bediuzzaman Said Nursi explains the real "tawakkul".It's worth to read :

" Belief is both light and strength. Yes, one who acquires true belief may challenge the whole universe and be saved from the pressure of events in accordance with the strength of his belief. Saying, “I place my trust in Allah,” he travels through the mountainous waves of events in the ship of life in complete safety. He entrusts all his burdens to the hand of power of the Absolutely Powerful One, voyages through the world in ease, then takes his rest in the Intermediate Realm. Later he may fly up to Paradise in order to enter eternal happiness. Otherwise, if he does not rely on Allah, rather than flying, the burdens of the world will drag him down to the lowest of the low. That is to say, belief necessitates affirmation of Divine unity, affirmation of Divine unity necessitates submission to Allah, submission to Allah necessitates reliance on Allah, and reliance on Allah necessarily leads to happiness in this world and the next. But do not misunderstand this, reliance on Allah is not to reject causes altogether; it is rather to know that causes are a veil to the hand of power and have recourse to them. Knowing that attempting causes is a sort of active prayer, it is to seek the effects only from Almighty Allah, recognize that the results are from Him alone, and to be thankful to Him.
Those who place their trust in Allah and those who do not, resemble the two men in this story:
One time two men loaded heavy burdens onto both their backs and heads, and buying tickets, boarded a large ship. As soon as they boarded it, one of them left his load on the deck, and sitting on it guarded it. The other, however, since he was both stupid and arrogant, did not put down his load. When he was told: “Leave that heavy load on the deck and be comfortable,” he replied: “No, I won’t put it down, it might get lost. I am strong, I’ll guard my property by carrying it on my head and back.” He was told again: “This reliable royal ship which is carrying you and us is stronger, it can protect it better than you. You may get giddy and fall into the sea together with your load. Anyway you will gradually lose your strength, and by degrees those loads will get heavier and your bent back and brainless head will not have the power to bear them. And if the Captain sees you in this state, he will either say that you are crazy and expel you from the ship, or he will think you are ungrateful, accusing our ship and jeering at us, and he will order you to be put into prison. Also you are making a fool of yourself in front of everyone. For the perceptive see that you are displaying weakness through your conceit, impotence through your pride, and a****ment and hypocrisy through your pretence, and have thus made yourself a laughing-stock in the eyes of the people. Everyone’s laughing at you.” Whereupon the unfortunate man came to his senses. He put down his load on the deck and sat on it. He said to the other: “Ah! May Allah be pleased with you. I’ve been saved from that difficulty, from prison, and from making a fool of myself.”
O man who does not place his trust in Allah! You too come to your senses like that man and place your trust in Him, so that you may be delivered from begging before all the universe, trembling before every event, from pride, making a fool of yourself, misery in the hereafter, and the prison of the pressures of this world..."
