Commentary
The ष् substitution does not take place in the स् of सिच् of the Intensive.
Thus सेसिच्यते and अभिसेसिच्यते ॥
Question:- The स of the reduplicate should be changed into ष by 8.3.65, in अभिसेसिच्यते, and the स of the root should be changed into ष by 8.3.64. Because सिच् is one of the roots taught in 8.3.65, and therefore, as this latter rule prevents the operation of 8.3.111 i. e. पदादि स so far as it goes, so it would prevent also the operation of this rule and the form ought to be अभिषेषिच्यते ?
Answer:- The ष ordained by 8.3.65 prevents only the operation of पदादि स of 8.3.111, and the स of this rule. Therefore the present prohibition is of universal application.
Why do we say in the Intensive. Observe अभिषिषिक्षति ॥
