“Emuna can be divided into three main levels:
1. Basic-level emuna: This is the firm belief that everything comes from Hashem by way of perfect Divine Providence, even the tiniest and most seemingly insignificant event.
2. Intermediate-level emuna: In addition to flawless basic emuna, the intermediate believes that everything Hashem does is for the very best.
3. Upper-level emuna: In addition to solid basic and intermediate level emuna, the upper-level individual believes that Hashem does everything for a specific purpose, and tries to understand the message within whatever Hashem does.”
~ The Garden of Emuna
