Prasidhyati means you increase. What is that? Utsāha, endeavor, "In this life I must fulfill my mission of Kṛṣṇa consciousness." That is called utsāha. Dhairya. Don't be agitated because it is not giving result immediately. Just patiently go on working. Utsāhād dhairyān niścayāt. Niścayāt means to have full faith in the words of Kṛṣṇa. Kṛṣṇa says, kaunteya pratijānīhi na me bhaktaḥ praṇaśyati (BG 9.31). This is called full faith that, "Kṛṣṇa has said that if I am in devotional service, I will never be lost. Kṛṣṇa will give me protection." Kṛṣṇa says. Ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi (BG 18.66). To have faith, this is called surrender. Not that, "Oh, Kṛṣṇa says, but may not be able to protect me." No. Kṛṣṇa is able. He is all-powerful, omnipotent. He can give you protection. When He says that ahaṁ tvāṁ sarva-pāpebhyo mokṣayiṣyāmi, that is a fact. This is called niścayāt, "Certainly Kṛṣṇa will give me protection." Not that, "Because I do not see Kṛṣṇa, I do not know whether Kṛṣṇa will give me protection." No. That word is sufficient. This is called niścayāt. Utsāhād dhairyān niścayād tat-tat-karma-pravartanāt.
But you must follow the rules and regulation, as it is enjoined in the śāstra. Not that, "Kṛṣṇa will give me protection, and I may do whatever I like. I can eat anything I like, I can do anything I like." Just some rascal advises that, "There is no such thing, restriction, in the self-realization. You can eat anything, you can do anything." People like that program. And as soon as there is restriction, they do not like. Because we put so many restriction, I am called, in the Western world, "Swāmījī, you are very conservative." So we have to become conservative, follow the rule. Not that we give liberty that, "Whatever you like, you do, and at the same time you make progress, spiritual life." That is not possible.
