Vyavasayatmika buddhih, fixed-up resolution. Fixed-up resolution. If we become fixed up in this resolution, that "Whatever we have heard from my guru, the representative of Krsna, I must execute it. I do not care for my personal convenience or inconvenience. This is my life and soul," then your life is perfect.
From Srila Prabhupada's lecture on Srimad-Bhagavatam 1.8.48 — October 28, 1974, Mayapur
