“The lazy, the dull-witted, the happy-go-lucky, those plagued by disease, the slumberous, and the lustful—these six are excluded by śāstra [i.e., they lack the qualifications needed to follow the teachings given in the śāstra and thus the teachings of the śāstra are not applicable to them; they will not attain the ideals taught in śāstra, and those who wish to attain such ideals should avoid their association].”
