妙法蓮華經玄義 3.47

3.47

若能親近善友，從其聞隨順方便法，內心正觀，信佛菩提，信善說法，信僧清淨功德，是說信寶。說色無常，乃至說識無常，是說信陰。知有苦、集、滅、道，是說信諦。若如是即住頂，若不如是即頂退。

If one can associate with a good spiritual friend, hear from them the methods of adaptable expedients, internally contemplate correctly, believe in the Buddha's bodhi, believe in the well-expounded Dharma, and believe in the pure merits of the Saṅgha, this is called believing in the jewels. Stating that form is impermanent up to stating that consciousness is impermanent—this is called believing in the aggregates. Knowing that there are suffering, arising, cessation, and path—this is called believing in the truths. If it is like this, one abides in Summit; if not like this, then there is retrogression from Summit.
