US-P03.002ab आत्मनोऽन्यस्य चेद् धर्मा अस्थूलत्वादयो मताः ।US-P03.002cd अज्ञेयत्वेऽस्य किं तैः स्यादात्मत्वे त्वन्यधीह्नुतिः ॥
In plain words
If attributes like non-grossness belong to something other than the self, and that other thing is unknowable, what use are those traits? If they belong to the self, then all notions of otherness are denied.
Close to the Sanskrit
If the attributes such as non-grossness are considered to belong to something other than the self, if it is unknowable what would be the use of those to it? But if they belong to the self, there is a denial of other cognitions.
