"Conceals his secrets" means he does not tell his secrets to others.

Commentary on the First Discourse on Analytical Knowledge
38. In the seventh, "this is my mental sluggishness" means when mental sluggishness has arisen, he knows "this is my mental sluggishness" according to its intrinsic nature. "Internally contracted" means accompanied by sloth and torpor. "Externally distracted" means distracted among the five types of sensual pleasure. "Feelings" and so on are taken by way of the roots of obsession. For feeling is the root of craving, since craving arises by means of happiness; perception is the root of wrong view, since wrong view arises regarding an obscure object; applied thought is the root of conceit, since conceit as "I am" arises by means of applied thought. "Suitable and unsuitable" means helpful and unhelpful. "Sign" means reason. The remainder is of manifest meaning everywhere.
