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, "Swamiji, you are very conservative." So we have to become conservative, follow the rules. 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.
